ABSTRACT:
The present invention discloses a process of forming glass, glass-ceramic or ceramic matrix, fiber reinforced composite articles. The method comprises preparing both the matrix and the reinforcement into fibers, which are then chopped into relatively short lengths. These chopped fibers are then formed into hybrid felt papers comprising a mixture of both reinforcing fibers and matrix fibers. These felt papers are then cut into preforms and stacked one on top of the other to form a lay-up. The lay-up is then placed in a die and densified to form the composite article.
