Pre-impregnated roving (TowPreg) are reinforcement fibres into which a resin system has been impregnated. TowPreg is used mainly in winding machine and equipment for manufacture pressure vessels, sticks, tubes and profiles. The resin systems in TowPreg react very slowly at room temperature. TowPreg resins can only be fully cured by heating them to the prescribed curing process.
