UV-CURED PULTRUSION PROCESSING OF GLASS-REINFORCED POLYMER COMPOSITES

摘要

A novel process was developed to adapt the pultrusion process to utilize radiation polymerization instead of thermal curing. Using UV-light and a methacrylate-based, 3-D-network copolymer matrix, 0.5mm diameter round quartz-fiber-reinforced-composite profiles were formed at a rate of 1.25mm per second. Faster rates resulted in partial curing. Materials were produced with various amounts of reinforcement, and evaluated in tension and in three-point bending. Mechanical properties varied linearly with fiber content, approaching the rule of mixtures.
