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, 0.5 mm diameter round quartz‐fiber‐reinforced‐composite profiles were formed at a rate of 1.25 mm 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.
