ABSTRACT:
A method of molding a hollow, fiber reinforced glass matrix composite article. Reinforcing fibers are placed in a mold cavity. A billet of high temperature stable glass matrix material is heated above its flow point. The thus heated matrix materials is flowed into the mold cavity from a point inside of the article being formed and at the relative midpoint along its vertical axis. Improved article tolerance control and minimized article preform fiber disturbance is achieved.
