PRODUCT INFORMATION : PREPREGS DELIVERING THE FUTURE OF COMPOSITE SOLUTIONS PREPREGS contact@gurit.com www.gurit.com

INTRODUCTION Gurit’s long history supplying prepregs to the wind energy, transportation and marine industries has allowed Gurit to lead the way by introducing the next generation of prepregs, specifically designed to make component manufacture faster, easier and cheaper. Pre-impregnated materials (prepregs) are reinforcement fibres or fabrics into which a pre-catalysed resin system has been impregnated by a machine. The resin systems in these materials react only very slowly at room temperature, allowing a long shelf life and are cured by heating them to the prescribed elavated temperature....
