Chomarat will present two new applications using its C-PLY carbon multiaxial fabric – a drone wing and a kayak – at the CAMX 2017 exhibition in Orlando, Florida, USA, on 12-14 December.
The drone wing for DASH X, a Class II UAV, was created in partnership with VX Aerospace and Northrup Grumman. The drone can be folded and stowed inside a cylindrical container that is carried and deployed from a tactical aircraft. C-PLY is used in the construction of the wing, the horizontal stabilisers, the vertical fin and all of the control surfaces.
“When it comes to wing skins, there is not a better material,” says VX Aerospace Chief Engineer Bob Skillen. “The extremely thin non-crimped laminate with customisable ply angles is perfect. Strength and stiffness are tailored for the loads. There are no weight and performance compromises created by undesired ‘off-axis’ ply angles. No other hand-placeable material can do this.”
The ultra-light, all-carbon kayak is the product of a collaborative project with Confluence Outdoor. C-PLY was chosen for its mechanical properties, which are said increase the kayak’s performance ten times compared to a classic construction.
“We chose C-PLY for the incredible mechanical properties of the non-crimp fabric,” confirms Oliver Wainwright, Product Engineer at Confluence Outdoor. “The ability to reduce the number of plies to have strength that is equal to that of its woven counterparts has helped us produce a lightweight kayak that can push the boundaries of our sport and achieve something that has never been done successfully by anyone else. The added benefit of being able to choose the fibre angle allows us to place material in an optimal position for our boat shape and get the directional stiffness we require.”
