A Small-Scale Test for Fiber Release From Carbon Composites,

Abstract

The release of electrically conductive fibers from resin carbon fiber composites presents a potential problem to electronic equipment. A test method was developed to determine fiber loss from pyrolyzed composites. Eleven composites consisting of woven and unwoven carbon fiber reinforcement and different resins were subjected to the bum and impact test device. The composites made with unidirectional tape had higher fiber loss than those with woven fabric. Also, the fiber loss was inversely proportional to the char yield of the resin. This technique provides a method to determine relative fiber loss with different resins and fiber construction. (MM)
