A review of the techniques for molding fiber reinforced thermoplastics RTP is presented, and the potentials for their use are discussed. RTP molding materials are available for the production of superior moldings by the use of conventional plunger and screw type injection machines. The addition of fibers generally yields a marked improvement in the physical properties of the molded product, approaching and sometimes exceeding the strength and durability of molded thermosets, some non-ferrous metals, and certain alloys. Materials chiefly applicable are glass and asbestos fibers, and the following resins - ABS, acetals, acrylics, nylons, polycarbonates, polyethylenes, polypropylenes, styrenes, fluorocarbons, chlorinated polyethers, urethanes, polysulfones, vinyls, and lubricated thermoplastics. The properties of resinreinforcement formulations made by several suppliers are given. The report also includes 53 references and an extensive supplemental bibliography. Appendixes mention several patents, applicable specifications, and known suppliers of RTP. Author
