Abstract
A composite molding apparatus for high pressure co-cure molding of lightweight honeycomb core composite articles having ramped surfaces utilizing low total density, stabilized ramped honeycomb cores. The composite molding apparatus is a semi-rigid molding assembly that includes a rigid base member and a complementary semi-rigid mold member that is formed from a combination of layers of fiber-reinforced elastomeric material and unreinforced elastomeric material. The semi-rigid mold member further includes internal rigid reinforcement inserts formed from a structurally rigid material and having a configuration that matches the configuration of the ramped surfaces of the honeycomb composite article. The rigid reinforcement inserts are interleaved between the layers of fiber-reinforced elastomeric material and/or unreinforced elastomeric material forming the semi-rigid mold member. The rigid reinforcement inserts of the semi-rigid mold member provide symmetric pressure distribution over the ramped surfaces of the honeycomb core and the overlayed composite prepregs during the high pressure co-cure process.
