ABSTRACT:
A laminate material for lighter-than-air vehicles includes a liquid crystal polymer fiber layer, a polyimide layer secured to the liquid crystal polymer fiber layer; and a polyvinylidene fluoride (PVDF) layer secured to the polyimide layer. The layers are secured to one another with a polyurethane adhesive. Adjacent laminates may be secured to one another by a PVDF cover tape on the exterior surfaces and a structural tape on the interior surfaces. The structural tape includes a liquid crystal polymer fiber layer and a polyimide layer to ensure the integrity of the vehicle. An alternative material may include a liquid crystal polymer fiber layer and a polyvinylidene fluoride (PVDF) layer disposed on both sides of the liquid crystal polymer fiber layer.
