Cutting Tools for Composites

Machining composites presents unique challenges compared to metals. Reinforcement fibers are abrasive, shortening tool life. The plastic matrix carries away little heat, unlike metal chips, and overheating can melt the matrix.

Advanced Technologies Supplement: Processes Reduce Composite Costs

Composites engineers are expanding their craft to build more complex, durable parts at higher production volumes. One way they are achieving this objective is by using infusion-molding processes based on Resin Transfer Molding (RTM) and Vacuum Assisted Resin Transfer Molding (VARTM).
