| description | A novel procedure for molding composite structures is disclosed wherein the finished part. exhibits a net shape geometry requiring minimal further machining and displaying enhanced consolidation and surface characteristics. A composite preform having a follow core portion containing a polymer insert is introduced into a mold cavity. One end of the preform core is sealed and the preform together with the polymer insert is heated to melt the composite matrix and core polymer. Pressure is applied to the core at the other end of the part, causing radial expansion of the part against the molded cavity and consolidation of the composite into a finished part. A product finished part is also disclosed and is useful as a component of an orthopedic implant. |
