Combining Snap-Cure Technology and Reclaimed Carbon Fiber to Address Next Generation Prepregs



Carbon fiber prepregs continue to make inroads into automotive applications with improved and automated processes.  The next generation prepregs will utilize current snap-cure resins and optimized reinforcements.

SGL has developed a snap-cure resin system in conjunction with application specific reinforcement options including recycled or reclaimed carbon fiber waste.  These options allow the user to utilize continuous fiber prepregs for spot specific reinforcement while utilizing lower cost reinforcements in less structural areas.  The end result is cost effective solution where key attributes such drape, flow, strength and stiffness can be achieved.
