Abstract:
A method of fabricating a pre-ceramic preimpregnated composite material comprising a continuous woven fiber and a discontinuous ceramic fiber matrix for subsequent curing and component construction, said method comprising:a) preparing a mixture of discontinuous fibers and a ceramic precursor resin, said precursor resin present in a quantity sufficient to substantially saturate subsequently adjacent woven fiber lengths;b) introducing the mixture to a situs between an upper length of woven fiber and a lower length of woven fiber in alignment with each other while effectuating linear movement of said upper and lower lengths and moving said lengths toward each other; andc) compressing and retaining said upper and lower lengths of woven fiber adjacent the mixture there between in a sandwich configuration for forcing an amount of ceramic precursor resin from the mixture to thereby substantially saturate the woven fiber with ceramic precursor resin.
