Abstract
A preimpregnated material has a reinforcement substrate impregnated with a thermoset resin mix which includes an initiator susceptible to light in the visible range. The material has cover films in the conventional manner but at least one of them is opaque whereby to protect the material from premature hardening. It gels and cures on exposure to ordinary daylight. The material has wide applicability in patching or locally reinforcing, and in laying-up laminating processes. A preferred mix has a polyester resin, or small amount of a thickener and a photoinitiator system comprising tribenzylamine, rosin and a benzoyl substituted-oxime carbonate ester.
