Measuring Method for Fuzz Mass of Carbon Fiber Tow

Abstract

In order to quantitatively test fuzz degree of carbon fiber (CF) tow, a measuring method for fuzz mass of CF tow was developed, and the testing device was built. Fuzz mass of two kinds of domestic T800-grade CF were tested using the established method. The effects of spreading width of CF tow, tension and fuzz-adsorption material on the fuzz mass of the two fibers were investigated. Several kinds of imported, domestic T700-grade CF and T800-grade CF were tested using optimized testing conditions. The experimental results show that the testing method is easy to operate and has wide applicability. Under 1-2N tension, 0.1-0.6mm pore size of sponge and 1-4N load applied on sponge, the measured values of T800-grade CF with 12K yield are reasonable. For CF tow with high fuzz mass, certain spreading width makes fuzz inside fiber bundle expose, which is needed to ensure the accuracy of testing result.
