.... Both carbon and graphite fibers are produced as untwisted bundles called tows. Common tow sizes are 1, 3, 6, 12, and 24k where k = 1000 fibers. Immediately after fabrication, carbon and graphite fibers are normally surface treated to improve their adhesion to the polymeric matrix. The mechanical...
