Abstract
An improved pultrusion process for preparing composites comprises combining polymer precursors in a mixer and continuously introducing the resulting mixture, together with reinforcing fibers, into an impregnation chamber maintained under conditions such that the mixture remains in liquid form of low viscosity. The impregnated fibers are continuously withdrawn from the chamber through a die in which polymerization of the precursors takes place to form the desired composite.
