• New technology for marine composites proven to reduce time and cost in manufacturing through out-of-autoclave processing

Hexcel Corporation (NYSE: HXL) has developed a new technology for out-of-autoclave (OoA) processing that delivers a game-changing reduction in process time and cost for marine manufacturers without compromising mechanical performance. Hexcel has leveraged its experience in aerospace and wind energy to develop its new G-Vent technology for OoA processing of highly loaded, thick section marine structures such as masts, foils, and wind-assisted ship propulsion (WASP) components. Hexcel’s full range of marine prepregs are now available with integrated G-Vent technology, reducing the requirement for debulking steps and ensuring extremely low porosity (<1%) irrespective of the laminate thickness.

To evaluate the new technology, Hexcel completed a test program with Q.I. Composites, a world leader in non-destructive testing in performance marine applications. The program evaluated HexPlyÒ 40- layer prepreg samples prepared with G-Vent technology. Carbon fiber panels made with no debulking revealed approximately three times less porosity than those using a typical 10-minute debulk with every second ply. Ultrasonic and CT scan analysis by Q.I. Composites confirmed the void content results with porosity levels in line with state-of-the-art autoclaved carbon prepreg foils. Key tensile, compressive and interlaminar shear strength results were also higher for the G-Vent panels.

“We evaluated the quality of thick laminates produced with G-Vent and found that they are comparable to laminates made in an autoclave as per best practice in the market,” said Stefano Beltrando, CEO, Q.I. Composites. “Even more impressive, they were achieved with no debulking.” Tom James, Business Development Manager at Hexcel, said, “We are absolutely delighted with the feedback from Q.I. that confirms our own test data and positions G-Vent technology as a leading OoA process enabler for high-performance thick laminate structures. G-Vent provides a faster and more cost-effective manufacturing route for large marine structures with absolutely no compromise in mechanical performance.”

Hexcel Corporation hosted customers and public officials at its manufacturing site in the Midparc Free Trade Zone in Casablanca as the company broke ground on an expansion that will double the size of its existing engineered core manufacturing operation in Morocco to meet increased demand from aerospace customers for lightweight advanced composites.

The expansion, announced in September 2021, is expected to be completed in early 2023. The plant size will double to 24,000 square meters and employment is expected to increase from 120 to 400 people when the expansion is completed.

The Casablanca facility was built as part of Hexcel’s ongoing worldwide investment to create a diversified and robust global supply chain to support aerospace customers’ growing demand for engineered core. At the plant, Hexcel transforms lightweight honeycomb materials into engineered core parts to reinforce structures in the aerospace industry, particularly for aircraft, engine nacelles, and helicopter blades.

At the event, Thierry Merlot, Hexcel President – Aerospace for Europe, MEA/AP & Industrial, said, “We are pleased to celebrate this milestone with our customers and with the local community. The increased demand for lightweight, aerodynamic, advanced composites is growing, and our customers including Safran, Airbus, Airbus Atlantic, Boeing and Spirit AeroSystems have shown confidence in our ability to meet that demand. We appreciate the support from them as well as from the Ministry and everyone in the local community who continue providing us with the opportunity to further our investment in Morocco. The very successful establishment of Hexcel, the qualification of the workforce, the support of the state and the proximity of our customers have been real assets to launch this extension of our site in Casablanca.”

After thorough consultation with the exhibitors and partners of the event, JEC Group has decided to postpone the 2022 edition of JEC World. The world’s leading composites event will now take place from May 3rd to 5th, 2022, at the same venue Paris Nord Villepinte, as well as online via the JEC World Connect digital platform.

JEC World gathers the whole value chain of the composite materials industry in Paris, France every year and is “the place to be” for composites professionals from all over the world. The event brings together not only all major global companies, but also innovative startups in the field of composites and advanced materials, experts, academics, scientists, and R&D leaders. JEC World is also the “festival of composites”, offering a unique showcase of what composites can offer to various application sectors, from aerospace to marine, from construction to automotive, and an unlimited source of inspiration for participants from these industries.

“We are fully dedicated to supporting the composites industry and to fostering its development via our events and media activities. Exhibitors and partners are strongly supporting JEC World, their leading event and want to meet in person in 2022 to activate business, share knowledge and highlight innovations. Postponing from March to May is a way to offer improved conditions to satisfy the industry requirements for such a trade fair as JEC World”, says Eric Pierrejean, CEO of JEC Group.

The JEC World team has decided to postpone the event after conducting a survey of its exhibitors and partners, confirming that a large majority is in favour of the new dates in May. As already planned, for three days, the event will offer for the first time a digital platform, JEC World Connect, in parallel to the in-person event in Paris for an augmented digital experience. Even after the show, via the JEC Web TV, unique content will be available to extend the reach of the event.

“Our main concern is to create the best possible conditions for our participants for successful networking, inspiration and business success. With a postponement of eight weeks we can enable this and offer to the industry the event it deserves. Taking the decision now, after consultation of all exhibitors, was necessary to give them planning and preparation visibility,” adds Thomas Lepretre, VP Events, Sales and Operations.

Strict protective measures will make the industry meeting possible at the International Conference on Cellulose Fibres in Cologne on February 2 and 3, 2022. The latest innovations will be shocased: from hygiene and textiles to non-wovens and carbon fibre alternatives to lightweight construction applications. Online participation is also possible.

Cellulose fibres show an increasingly expanding wide range of applications, while at the same time markets are driven by technological developments and political framework conditions, especially bans and restrictions on plastics and increasing sustainability requirements. The conference provides rich information on opportunities for cellulose fibres through policy assessment, a session on sustainability, recycling and alternative feedstocks as well as latest development in pulp, cellulose fibres and yarns. This includes application such as non-wovens, packaging and composites.

Live at the conference, host nova-Institute and sponsor GIG Karasek GmbH will grand the “Cellulose Fibre Innovation of the Year” award to one of six highly interesting products, ranging from cellulose made of orange and wood pulp to a novel technology for cellulose fibre production. The presentations, election of the winner by the conference audience and the award ceremony will take place on the first day of the conference.

The conference sessions reflect the current topics of industry and research. “Strategies and Market Trends” provides an overview of the rapid development of cellulose fibres and their technological progress across the fibre market. An analysis of the key cost components of these fibres to benchmark against current cost levels will highlight future opportunities and challenges for novel textile fibres. The session will conclude with an overview of the industry's recent strategies to defossilize the fibre market.

The session “New Opportunities for Cellulose Fibres in Replacing Plastics”, focusses on questions such as: “What impact does the ban on plastics in single-use products have on the industry?” and “What are the latest regulatory issues and policy opportunities for cellulose fibres?”. This part of the conference presents new opportunities for the replacement of fossil-based insulating materials with cellulose-based technologies suitable for use in a variety of applications, from aerospace to mobility and construction.

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

Knopf’s Sohn, a contract finisher of technical textiles, has installed a fully automated Montex stenter at its plant in Helmbrechts, Germany.
Knopf’s Sohn is processing technical textiles for the automotive, aerospace, home furnishings and workwear markets, based on wool, cellulose, polyamide and polyester fabrics, along with elastane blends, in weights of 80-800gsm.

The Montex machinery range is constantly being upgraded to meet evolving customer needs for greater automation, ease of operation and energy optimisation. The latest ten chamber line at Knopf’s Sohn, with a working width of up to 2.0 metres, was engineered to specific requirements in order to accelerate the company’s move to fully automatic control of its production, and high scaffolding was required for its installation.

The line benefits from two integrated ECO Booster modules to provide high energy savings. These compact, air-to-air heat exchangers, installed within the roof structure of the line, exploit energy from the exhaust gas to preheat up to 60% of the incoming fresh air entering the stenter.

The use of a single ECO Booster unit has been calculated to save up to 35% in energy costs, based on fixation processes. Fully automatic operation, set at the Monforts Qualitex control unit, ensures there is no additional burden on the machine operator.

The line is powered by Exxotherm indirect heating, which practically eliminates the yellowing which can be experienced during the treatment of certain polyamide and elastane-based fabrics, and is also equipped with a Conticlean circulating air filter system for constant high drying capacity.

Software
The latest Qualitex visualisation software offers operators reliability and easy control with its full HD multi-touch monitor and slider function, dashboard function with individual adaptation to operating states and faster access to comprehensive recipe data management.

With the Monformatic control system, the exact maintenance of the dwell time in combined treatment processes (drying and heat-setting) can be monitored. When the heat-setting point is reached, the fan speed is automatically adjusted, keeping energy consumption fully under control.

Hexcel, a global leader in advanced composites technologies, announces the successful maiden flight of a lightweight camera drone, developed using Hexcel HexPly® carbon fiber prepregs. The composite drone was developed by a team of students from the University of Applied Sciences Upper Austria in Wels with composite materials supplied by Hexcel Neumarkt in Austria.

A team of six students in the university’s lightweight construction and composite materials course was responsible for the complete design, engineering, and manufacture of the camera drone over a period of 18 months. Hexcel materials and optimization of the composite engineering enabled the team to reduce the composite structural mass by an impressive 42% compared to similar drones.

Hexcel Neumarkt was one of eight industrial partners supporting the university team throughout the project, providing all carbon fiber prepreg materials used for the drone’s landing gear as well as the fuselage. The ultra-lightweight 32g landing gear was laid up and cured in the press, whereas the fuselage was autoclave cured by the student team using Hexcel HexPly M901 and HexPly M78.1 prepreg resin systems with a combination of woven and unidirectional carbon fiber reinforcements.

With the development of Unmanned Aerial Vehicles (UAV) as a key emerging market and innovation space in the transportation sector, Hexcel’s collaboration with the University of Applied Sciences Upper Austria team not only creates an important link with the next generation of lightweight composite engineers but also highlights the weight saving and structural benefits of Hexcel composite material solutions.

"The massive weight saving achieved with their updated version of the camera drone is a fantastic achievement by the student team," said Michael Rabl, Dean of FH Wels of the Upper Austria University of Applied Sciences. "The joint study not only illustrates the wide range of complex and innovative composite techniques present in the drone sector but also presents the opportunities that exist for further development in the wider Urban Air Mobility (UAM) and aerospace composites markets.”

Hexcel congratulates the project team which includes Lukas Weninger, Karl-Heinz Schneider, Jakob Schlosser, Matthias Thon, Marla Unter, and Simone Hartl on an exceptional piece of lightweight composite design and thanks them for showcasing the contribution of Hexcel materials with a presentation and drone flight. Johanna Arndt, research and technology group leader at Hexcel Neumarkt, said, “It was a great pleasure to work with the team who were very cooperative and self-motivated to succeed. Watching the drone just fly around the Neumarkt plant was just great.”

Hexcel manufactures a complete range of carbon fibers, dry carbon UD tapes, specialty reinforcements, prepregs, and honeycomb core materials, providing customized manufacturing options for new UAM applications that combine aerospace reliability with the high-rate production required. Hexcel composite materials are the ideal solution for the lightest and most efficient cost-competitive transportation vehicles of the future.
