Abstract
1353058 Boron filament polyimide laminate T R W Inc 19 April 1971 [25 May 1970] 25769/71 Heading B5N [Also in Division C3] Boron filament polyimide laminates are made by applying a solution or dispersion in an organic solvent of a heat-curable polyamideacid prepared by reacting a polyamine, a polyanhydride and monoanhydride where R is H or C 1 -C 5 alkyl, in approximately stoichiometric proportions of polyamine to total anhydride, to a drum covered with a terephthalic acid polyester film, applying a scrim cloth to the coated film, partially drying, applying further solution or dispersion, partially drying, winding boron filaments on to the drum (208 filaments/inch) and more solution or dispersion applied. The assembly is then partially dried, removed from the drum, further dried and cut into rectangular pieces which are pressed to form a 10 ply laminate at 315 C. and 100 p.s.i. Reference is made to Specifications 1,241,445 and 1,243,643.
