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.”

  • Reduction of material usage by up to 50 percent through innovative draping strategy in the production of fibre composite materials

In fibre reinforced plastic (FRP) production, stamp forming is one of the most economical processes for automated large-scale production, e.g. in the BMW i-series. However, the current processes are susceptible to draping errors and a high proportion of waste.

  • Reduction of material usage by up to 50 percent through innovative draping strategy in the production of fibre composite materials

In fibre reinforced plastic (FRP) production, stamp forming is one of the most economical processes for automated large-scale production, e.g. in the BMW i-series. However, the current processes are susceptible to draping errors and a high proportion of waste. An innovative process developed at the Institut für Textiltechnik of RWTH Aachen University, short ITA, can now significantly reduce the scrap rate and reduce the waste rate of high-priced reinforcing textiles, such as carbon fibre textiles, by up to 50 percent. Sven Schöfer from ITA achieved this effect with his work "Development of a textile-based material feed to increase the preform quality during stamp forming of reinforcing layers". On 10 September 2019, he won the third AVK Innovation Prize in the "Research and Science" category at Composite Europe in Stuttgart, Germany.

Current process
In stamp forming, clamping grippers are usually used in industry to feed the stacked individual layers to the forming process and position them on the lower tool via a clamping frame or hold-down device. Due to the clamping grippers, the cutting proportion of cost-intensive reinforcing textiles is high, as additional material at the textile edge is necessary with clamping systems. Other approaches to feeding the reinforcing semi-finished product during forming and simultaneously improving the draping quality are also not economical: they are usually only designed for certain textile cuts, cannot be automated, are prone to errors or are expensive special solutions.

There is currently no system in the industry that can apply retention forces along a final contour with low waste and remains flexible in terms of geometry.

Innovative approach of Sven Schöfer
The innovative process developed by Sven Schöfer works with a detachable textile joint, a so-called tufting seam. It allows the single layers to slide off during the forming process under a retention force dependent on the seam design.

This reduces or completely eliminates draping errors in previously critical areas, even with complex preform geometries. This leads to a significant increase in preform quality and a reduction in scrap rates. The process is also highly efficient, as tensile forces can be applied to any component geometry on near-net-shape blanks. This reduces the material input by up to 50 percent.

LENZING™ fibers are fully biodegradable in water, soil and compost

  • Organic Waste Systems and TÜV confirm fiber biodegradability also in fresh water
  • All white LENZING™ Viscose, Modal and Lyocell fibers are now certified for all environments

  • Organic Waste Systems and TÜV confirm fiber biodegradability also in fresh water
  • All white LENZING™ Viscose, Modal and Lyocell fibers are now certified for all environments
  • Global legislators aim at limiting plastic waste persisting in the environment for centuries
  • EU Single-Use Plastics Directive partly regulates usage of plastic products
  • Biodegradable materials such as wood-based fibers are the best alternative to single-use plastics

The Lenzing Group received confirmation of the full biodegradability of its fibers in fresh water by the independent research laboratory Organic Waste Systems (OWS). The new and existing international certifications conducted by OWS and issued by TÜV Austria verify that LENZING™ Viscose fibers, LENZING™ Modal fibers and LENZING™ Lyocell fibers are biodegradable in all natural and industrial environments: in the soil, compost as well as in fresh and in marine water.

The biodegradability of cellulosic products and the synthetic fiber polyester was tested in fresh water at OWS according to valid international standards, e.g. ISO 14851. At the end of the trial period, LENZING™ wood-based cellulosic fibers, cotton and paper pulp were shown to be fully biodegradable in fresh water in contrast to synthetic polyester fibers. The fact that synthetic materials are not biodegradable leads to major problems in wastewater treatment plants and potentially marine litter. In turn, this not only harms fish and birds living in and close to the oceans but also all marine organisms and us humans.

“The Lenzing Group operates a truly circular business model based on the renewable raw material wood to produce biodegradable fibers returning to nature after use. This complete cycle comprises the starting point of the core value of sustainability embedded in our company strategy sCore TEN and is the ‘raison d’etre’ of our company”, says Stefan Doboczky, Chief Executive Officer of the Lenzing Group. “In living up to this positioning, we not only enhance the business of our suppliers, customers and partners along the value chain but also improve the state of the entire textile and nonwovens industries.”

Both the textile and nonwovens industries face huge challenges with respect to littering. If current trends continue, the oceans could contain more plastic than fish by 2050. Therefore, legislative bodies worldwide can no longer ignore the issue and have moved towards plastics legislation aimed at limiting the vast amount of waste. In response, European lawmakers issued the Single-Use Plastics Directive currently being transposed into national legislation in the EU member states.

Conventional wet wipes and hygiene products mostly contain plastic and were thus identified as one of the product categories to be singled out. Less polluting alternatives are generally encouraged by NGOs and legislators, e.g. products made of biodegradable wood-based cellulosic fibers. Plastic waste including microplastic can persist in the environment for centuries. In contrast, biodegradable materials are the best alternative to single-use plastics because they fully convert back to nature by definition and thus do not require recycling.
