Abstract

The methods used to synthesize thermoplastic resins for use as the organic matrix for resin-based thermoplastic composites are described. The synergism between the processing method chosen to prepare the composite and the synthesis route used to prepare the resin is emphasized. The synthesis and basic chemistry of commodity-type resins, such as polyamides, polyolefins, polycarbonates, polyacrylates, and acetals, used in composites are discussed. In addition, the chemistry of advanced resin systems, such as polyether ketones, polysulfones, polysulfides, and polyimides, used in high performance composite systems also are presented. Both true thermoplastic resins and pseudothermoplastic resins, that is, resins that undergo some reaction during procesing, are discussed. Several new and potentially important methods for preparing thermoplastic resins for use in composites are highlighted.
