Glass reinforced-polyester resin laminates were fabricated by means of artificial ultra-violet radiation at O C, and 25 C, and in direct sunlight. Benzoin, benzil and Garalyst sensitizers were used. The laminates produced had physical properties that compared favorably with those fabricated with conventional peroxidic systems. With U V curing systems, it was possible to obtain long pot-life and short gel periods, two requirements for laying up complex plastic structures. Physical properties and fabrication details are listed in accompanying tables.
