Introducing the next generation of Prepregs, specifically designed to make large composite component manufacture faster, easier and cheaper. Pre-impregnated materials (prepregs) are reinforcement fibres or fabrics into which a precatalysed resin system has been impregnated by a machine. The resin systems in these materials react very slowly at room temperature, giving rise to working times of many days or months. Prepreg resins can only be fully cured by heating them to the prescribed cure temperature. The accuracy of the machinery used to combine the fabric or fibre with the resin ensures that laminates produced from prepregs have more consistent and higher fibre contents than can be achieved by wet lay-up techniques. This allows the use of very tough, strong resin systems that would be too high in viscosity to be impregnated by hand.
The Composite Store can also supply a wider range of Prepregs and Glue Films than featured on this site. Please refer to the Gurit catalogue for the full range of what is available
