Developing a pultrusion process for fabricating composites using a graphite reinforced high-performance thermoplastic presents a technological challenge to the pultruder. Unlike conventional pultrusion of thermosets containing monomeric reactants and solvents which react in the pultrusion die causing polymerization, high-performance thermoplastic polymers either do not contain solvents or contain solvents which must be removed before polymerizing. In either case, consolidation is performed with rigid or
