To reduce weight, a combination of carbon fiber stitched biaxial fabrics and UD reinforcements is used wherever possible, with additional glass fiber reinforced laminate sections where radio-transparency or insulation from metallic parts is required.
The product : materials and processes
COBRA proposed a hybrid solution, combining both hollow and cored sections, for the flying wing. The main body of the aircraft comprises a PVC foam sandwich shell with a low-density EPS foam rib which, combined with a fully foam cored tail structure, delivers a complete airframe fractionally lighter than the customer''s challenging target.
