Abstract
A process for preparing a postformable composite article of a heat curable thermosetting polymer having a substantial length and a non-trivial uniform cross-sectional shape. The process includes controlling the pull rate and the temperature of the heating and cooling sections of the die in response to the viscosity and the cure kinetics of the thermosetting polymer composition and (2) the non-trivial shape of the article.
