Abstract: A versatile halogen-free flame retardant epoxy-based prepreg system was designed with snap cure capabilities along with a high Tg suitable for automotive racing applications. The newly designed system enables one to satisfy not only the requirements of the SFI 56.1 vertical burn test for both single and multi-ply laminates, but the more strict requirements of the UL94 V-0 flammability test as well. Additionally, the new prepreg system provides a clear high finish surface appearance when cured for added value to expand into other applications. The development of this new system as well as the system’s performance will be explored in this paper.
