EFFECT OF MILLING PARAMETERS ON SURFACE DEFECT FORMATION IN POLYMER COMPOSITES

摘要

The number of surface defects in the form of pulled and torn fibers as well as matrix chipping and matrix/fibers interface chipping is determined. The influence of milling parameters on the number of torn fibers and the percentage of defects in the material structure are analyzed. Carbon fiber reinforced plastics are used in this study. The obtained results show a significant relationship between the milling parameters and the produced defects. It is found that the number of defects significantly depends on the feed speed increase. Increase in cutting speed leads to a reduced number of defects.
