Aus der Branche

Cobra International, a leading manufacturer of advanced composite products for the watersports, automotive, marine, and industrial sectors, will highlight recent diversification into new composite markets at JEC World 2022, with exhibits ranging from VTOL drones to carbon fibre prosthetics.  Cobra will also demonstrate how it is working alongside automotive and water sports customers to further enhance the sustainability of products in these sectors.

High Volume Production Capacity for the UAV sector
Cobra will display a wing from the Swiftlet UAV. This compact tactical fixed wing UAV platform has a 5.5m wingspan and was developed by the Royal Thai Air Force and National Science and Technology Development Agency (NSTDA) for survey, monitoring and search and rescue operations. Cobra manufactured the 32kg Swiftlet composite airframe using a combination of CNC cut carbon sandwich internal structure and PVC foam sandwich skins using both high grade glass fibre and carbon fibre reinforcements.  

Sustainability Options for Automotive and Watersports
Sustainability has a been a key focus for the Cobra Waterports division and CAC, the Cobra automotive business unit. At JEC World 2022, Cobra will showcase the increasing material and process options it has developed with both bio-resin and natural fibre reinforcements variants presented alongside more traditional carbon fibre parts.

Visitors will be able to get up close to a new Bio SUP Wingfoil board featuring a basalt, flax, bamboo and GreenPoxy bio-epoxy construction created for partners NSP, as well as state-of-the-art compression moulded prepreg foils. Cobra’s first fully recyclable surfboard incorporating the Recyclamine® resin technology that Cobra was recognised for in the 2020 JEC Innovation Awards will also be on display alongside a new Audi e-tron foil by Aerofoils – the world’s safest electric hydrofoil board.

The CAC team (Automotive Business Unit of Cobra) will present a set of OEM mirror cap parts that showcase a range of carbon SMC, woven visual carbon, pure woven visual flax, hybrid flax-carbon and painted flax construction options for the same component.  Clear carbon aesthetic and structural parts including CAC made M-carbon components for the BMW S 1000 RR Motorcycle will furthermore underline the high quality and eye-for-detail for which CAC is renowned.

Carbon Prosthetics
An entirely new composite application for the company, Cobra will also show two composite prosthetic devices at JEC which were productionised by the in-house design and development team. Working alongside a leading Thai university and a medical device OEM, Cobra created a rapid and cost effective series production process for a lightweight carbon fibre prosthetic foot. In another example of lightweight composites creating major quality of life improvements, Cobra has also designed and manufactured a carbon and glass fibre prepreg foot support for Elysium Industries.

COBRA International is pleased to confirm its continued partnership with Fliteboard as the builders of the new Fliteboard Series 2.  

Conceived in 2016, the Fliteboard range of electric foiling surfboards has established a leading position in the eFoil market. In early 2021, Fliteboard announced a package of evolutionary improvements to the original award-winning design for which COBRA has installed significant additional manufacturing capacity.

With Fliteboard growing rapidly, and thousands of boards now delivered across more than 80 countries,  COBRA will continue to support Fliteboard with additional moulds and lean manufacturing production lines added to reduce customer lead times. In addition to this production capacity expansion, COBRA has successfully met the technical challenges set by the Fliteboard team to incorporate all the new Series 2 board features into the existing production processes.

Fliteboard’s first composite models used a carbon fibre and Innegra sandwich laminate over a moulded EPS foam core, combining maximum strength, stiffness, and durability with a low overall board weight. The same construction concept is used for the Series 2 boards, with several new finishes added to the range along with lighter colour matched EVA deck pads and upgraded latches on the carbon fibre board lid. New wood grain and metallic paint finishes have been introduced with COBRA’s semi-transparent paint system used to save weight and display the stunning hexagonal weave pattern of the carbon and Innegra reinforcement fabrics.

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.”
