The mechanical and tribological properties of CF/PPS composite filled with PA6

The mechanical and friction and wear behaviors of carbon fiber/polyphenylene sulfide (CF/PPS) composite and polyamide 6 (PA6)-filled CF/PPS (CF/PA6/PPS) composites were investigated. The addition of 2 vol%, 4 vol% and 6 vol% PA6 increases the bending strength of CF/PPS composite. In order to further understand the wear mechanisms, the worn surfaces of samples were analyzed by scanning electron microscopy (SEM). The experimental results indicated that the wear loss and the friction coefficient of CF/PPS composite decreased with the addition of PA6 particles. The main wear mechanisms under dry sliding condition are the plastic deformation and mechanical microploughing.
