Improved ram extruded composite products, methods of manufacture. The composite is a thermoset resin which is tailor-made for specific industrial applications. A typical composite is constituted of a phenolic resin which contains carbon fibers of various lengths where each length of fibers are oriented in a pre-selected, pre-determined orientation. The products are preferably made by ram-extrusion. A large variety of different types of fibers and resins are useful.

A fiber-reinforced rigid and solid phenolic thermoset resin composite having a longitudinal axis and having improved physical properties, including improved compressive strength, impact strength, and electrical properties which comprises a thermoset phenolic resin containing carbon fibers, said carbon fibers being a mixture of long fibers having a length of from about ¼″to about 2″, medium fibers having a length of from about ⅛″to about ¼″and short fibers having a length less than ⅛″, embeded, oriented and organized in the phenolic resin so that from about 75 to about at least 90% of the long fibers and from about 75°to about at least 90°of the medium fibers are oriented about 80 to 90% perpendicular to the longitudinal axis of the composite and the short fibers are randomly oriented.
