Abstract
Novel carbon-carbon laminate composite materials capable of significantly increased strengths in at least one predetermined direction of load are disclosed. The composites can comprise plies of resin impregnated woven carbon or graphite cloth material in combination with resin impregnated carbon or graphite filament unidirectional tape or can be fabricated from the unidirectional tape alone. Generally the unidirectional reinforcement of the tape plies provides higher strengths and moduli in specific directions which can be controlled during lay up of parts. The processes for obtaining the beneficial increase strength of unidirectional tape ply materials while avoiding fabrication problems resulting therefrom are also disclosed.
