Dragonplate high temperature carbon fiber sheets are comprised of a special carbon fiber/phenolic prepreg laminate that is formulated and processed to give excellent properties at temperatures much higher than standard epoxy products can withstand. These high temperature sheets maintain most of their rigidity up to 500 F, and can withstand short durations at much higher temperatures. Due to the phenolic resin system, these sheets are very flame retardant, and can survive short duration contact by direct flame. After long duration direct flame contact, mechanical properties will be reduced, but the shape is maintained. Sheet finish is textured on both sides.Please allow 10-15 days before these sheets ship.
