Chomarat fabrics at the KraussMaffei booth during K Messe 2019

Chomarat Group’s composite reinforcements will be featured at the KraussMaffei stand during the next K Messe in Düsseldorf. Chomarat has created a glass reinforcement adapted to the mass production of automotive parts, helping to lighten leaf springs by 60% compared to metal.

Automotive: Producing 60% lighter leaf springs for car's underbody
The new leaf springs made of composites are 60% lighter than their pendants made of steel thanks to KraussMaffei process and the involvement of a network of partners, including Chomarat with G-PLY™ glass reinforcement. Their strength can be deliberately increased in sections where it is required and the corrosion resistance offers further added value.

“We created the fabrics, when Engenuity developed the component, Huntsman supplied the matrix system made of epoxy resin, Johns Manville supplied the glass fibers, Schmidt & Heinzmann manufactured the preforms, Alpex designed the RTM mold and Hufschmied (Bobingen, Germany) took charge of post-mold processing of the component by milling. KraussMaffei has taken over the project management for Hengrui and coordinates the project with the partners.” Francisco De Oliveira at Chomarat explains.

COBRA delivers first 100 composite fuselage covers for cutting-edge drones

COBRA International is collaborating with HG Robotics, a leading drone manufacturer that specializes in unmanned aerial vehicles (UAVs) for the agricultural market, on a composite fuselage cover for the cutting-edge Tiger Drones.

Undertaking a full range of services with HG Robotics and having been involved from the outset: from the design and engineering through to the prototyping of the composite drone fuselage cover, COBRA has now delivered nearly 100 sets and will produce approximately 500 units throughout 2019.

The multi-rotor Tiger Drones typically carry spraying equipment and can also carry high definition cameras that provide a wide range of field information. Farmers can measure land profiles, identify any problem plants or areas and manage their cultivation in the most efficient way. The 420 mm square shaped fuselage cover protects the drone’s electronic controls and forms an aerodynamic fairing between the central fuselage and the craft’s 4 rotor arms.
 
The COBRA Design and Development team selected a composite laminate of glass fibre reinforcements for the cover – which don’t interfere with GPS signals used by the drone - and combined these with epoxy laminating resins in a hand laminated, vacuum bag consolidated production process.

COBRA also designed all of the mould tools for the project. The 2-piece aluminium mould was produced by one of COBRA’s long-term tooling partners. This metallic tooling provides an excellent surface finish to the part with absolutely minimal trimming and finishing required.   Moulded parts can go swiftly through a painting and clear coating process before final inspection and delivery to the client.

Danu Chotikapanich, CEO of COBRA International comments: “Our collaboration with HG Robotics is going well, and we are hoping to collaborate further with them on other multi-rotor and fixed wing VTOL (vertical take-off and landing) drone models in the future. These are COBRA’s first parts for the agricultural industry, and they provide an exciting vision as to just a few of the possibilities for lightweight composites in this area and also in the wider commercial UAV market as a whole.”

Innovations that will change the future of Building and Construction to be rewarded at JEC Innovation Awards in Chicago, June 20-22, 2017

Composites use in Building and Construction will be highlighted at JEC newest event dedicated to this specific Composites Industry next month in Chicago, IL, USA. The numerous and diverse benefits that these innovative materials bring to the Building Industry will help overcome the coming challenges such as, urbanization, increase of natural disasters (floods, storms, tsunamis, earthquakes…), along with the decrease of non-renewable raw materials and the high standard levels set by the society in terms of lightness and fluidity.

Composites use in Building and Construction will be highlighted at JEC newest event dedicated to this specific Composites Industry next month in Chicago, IL, USA. The numerous and diverse benefits that these innovative materials bring to the Building Industry will help overcome the coming challenges such as, urbanization, increase of natural disasters (floods, storms, tsunamis, earthquakes…), along with the decrease of non-renewable raw materials and the high standard levels set by the society in terms of lightness and fluidity. Composites Materials bring answers and opportunities to tackle those issues in sustainable, durable and reliable manners. Solutions like ease of fabrication (Owens Corning), structures durability (Biteam), anti-seismic reinforcement (DowAksa), use of end-of-life products such as recycled bottles of water (Premier Composites Technologies), aerial forms (Optima Projects Ltd) or again energy saving (Armageddon Energy).


Following its strategy to address every Composites End-user, the JEC Innovation Awards will reward these 6 Composites Innovators in Building & Construction that will change the way we build.
If the majority of submissions relied on glass fibers, which is common in the Construction field, we see an increased interest in carbon fibers, especially for structural applications. And similarly to all sectors of the composite industry, thermoplastics are gaining in importance in Construction. Therefore, to promote the growing use of composites as a construction material, 6 categories are awarded, covering a large panel of applications and possibilities.
