摘要

Machined surface properties of plain-woven C/C composites have been investigated. SEM observation results indicated that surface properties of the 0 2 layer predominantly controlled the machined surface finish. The 0 2 layer on the machined surface provided four types of feature; burnished, built-up residue , over-cut and smooth surface. The cutting forces depended on the rake angle and the fiber angle 0 1/0 2 as same as the unidirectional composite. All cutting conditions presented built-up residue which consists of broken fiber and matrix around the fiber on the machined surface. Measurement results indicated that break down percentage, the weight percentage of built-up residue in the weight of the work material, was significantly affected by the rake angle and the fiber angle 0 1/0 2. However, break down percentage could not vary the values corresponding to the cutting force.
