ABSTRACT:
Uncured thermoset composite reactants containing ultraviolet curable reagents may be effectively cured by pultrusion using a unique molding die which uniformly irradiates the uncured composites contained within the die. The die includes strategically positioned passageways communicating through the chamber walls of the die to the die chamber. The passageways are equipped with fiber optic cables connected to an ultraviolet generator at one cable end and ultraviolet discharging end for discharging ultraviolet radiation within the die chamber at an opposite cable end. Ultraviolet light conducted to the die chamber by the fiber optic cables uniformly initiates and catalyzes the uncured reactants to produce a fully cured thermoset composite. Uncured composite reactants may be continuously fed to the die as the cured composites are continuously withdrawn from the die.
