Abstract:
A method of making integrated, layered fiber reinforced ceramic matrix composite FRCMC armor comprising the steps of:(a) placing a quantity of FRCMC bulk molding compound into a female die of a mold, said FRCMC bulk molding compound comprising a pre-ceramic resin;(b) placing at least one sheet of woven fibers on top of said quantity of FRCMC bulk molding compound;(c) repeating steps (a) and (b) as desired;(d) pressing a male die of the mold onto the female die so as to mold said armor in a cavity formed between the female and male dies, said cavity having a shape corresponding a desired shape of the armor;e) heating the mold at a temperature and for a time associated with the pre-ceramic resin which polymerizes the resin to form a fiber-reinforced polymer composite structure;(f) removing the polymerized composite structure from the mold; and(g) heating the polymerized composite structure at a temperature and for a time associated with the polymerized resin which pyrolizes the polymerized composite structure.
