Abstract
A process for preparing shaped thermoplastic composite articles of continuous fibrous strand material in a polymeric resin matrix. The shaped composite articles are prepared by a pultrusion process involving contacting the strands with cyclic oligomers, for example cyclic polycarbonate oligomers, and then polymerizing the oligomers into high molecular weight polymer to produce a composite. The process provides for low melt viscosity impregnation of the strands with cyclic oligomers prior to formation of the high molecular weight resin matrix.
