Method of manufacturing a composite insert

A pre-packaged composite part comprising:

• a) a polymer mold joined to a carrier such that a cavity for accepting a composite insert composition is defined between the polymer mold and the carrier;
• b) a dimensionally stable composite insert comprising a composite insert composition provided with a shape by the polymer mold and the carrier,
• wherein said composite insert is adhered to the carrier, such that the carrier and the composite insert constitute a composite part, and the composite insert is disposed within the cavity such that the polymer mold remains covering at least a portion of the composite insert thereby forming a pre-packaging, which acts as an external protective covering for the composite insert;
• wherein the carrier is comprised of one or more of carbon fiber, fiberglass, plastics, metal, ceramic, paperboard and anisotropic materials;
• and the composite insert further comprises solid material, different from and separately introduced into the cavity from the composite insert composition, and molded with the composite insert composition, said solid material being incorporated discontinuously in the dimensionally stable composite insert at one or more selected positions such that the solid material is present in only portions of said insert.
