ABSTRACT:
A method particularly adapted for making a complex shaped composite component that has reduced bridging defects. The method comprises disposing a composite prepreg on to a substantially flat tool. The composite prepreg has a substantially flat section and at least one prepreg member extending from and substantially perpendicular to said flat section. A layer, at least about 125% of said composite prepreg height, of a said flowable particulate silicone rubber is disposed in substantially complete contact with the composite prepreg surface. The particulate silicone rubber has a flow rate of at least 0.6 gram/second through a 1.1 cm diameter pipe 7.6 cm long under applied pressure of 10.34 MPa at room temperature. The layer of solid flowable rubber is covered with a bag to effect a gas tight seal. The bag is exposed to pressures which are transferred to said prepreg by said solid flowable polymer. The composite prepreg is exposed to temperatures to form a composite component.
