Acta Metallurgica Sinica(English Letters) 1999年第5期12卷 886-890页

A study is carried out which analyzes the machinability of polymer matrix composites under an abrasive waterjet (AWj) and the associated erosive process or mechanism. It shows that AWj cutting can produce good quality kerf at high production rate if the cutting parameters are properly selected. A scanning electron microscopy (SEM) analysis of the cut surfaces reveals that the erosive process for the matrix material (resin) involves shearing and ploughing as well as intergranular cracking, while shearing is a dominant process for cutting the fibres in the upper cutting region but the fibers are mostly pulled out in the lower region.
