Process Control for Resin Transfer Molding (RTM).

Abstract

This document presents the results of the process control for a resin transfer molding (RTM) study. RTM is a composite materials processing method that involves placing a preform of dry reinforcement in a mold, injecting a thermoset resin into the mold, curing the resin, and demolding the finished part. This report describes the equipment and methodology for in-mold resin flow mapping and control. Mold port arrays are used to achieve directional control of in mold resin flow. A novel flow mapping system based on SMART Weave was implemented and tested. Combining the flow mapping and resin control schemes will lead to closed loop automation of the injection process.
