Composites. Prepregs. Determination of gel time Ingestion-build-52208 2 Typical competency areas1 Scope This International Standard specifies a method for the determination of the gel time of prepregs made of continuous reinforcement impregnated with epoxy and or unsaturated polyester resin. The method is applicable to most prepregs with a width in the range 300 mm to 1 000 mm. It is not suitable for very narrow prepregs (for example narrow tape), nor for prepregs with a low resin content. NOTE Other methods of measuring gel time exist. These
