摘要

Experimental values of the temperature on the wall and into the die were obtained for the pultrusion of a modified acrylic resin.The equation of continuity,and energy balance,coupled with a kietic expression for the curing system,are solved using difference method to calculate the temperature and the conversion profiles in the thickness direction in a rectangular pultrusion die.The effects of the process variables (d.g.pulling rate,die temperature,die thickness and content of fibers) on the performance of the pultrusion are evaluated.
