Development of new technology for the source elimination of contaminants in the plastic composites sector : RTM (ph.2)

Abstract

Most Québec companies in the reinforced plastic sector used contact moulding to fabricate composite articles made of polyester and fibreglass. This process in an open one, and results in high styrene concentrations in the ambient air.

This project was undertaken to promote the adoption of the resin-transfer moulding process, a process which uses a low-pressure, closed mould. This process results in substantially lower styrene emissions, but is more costly to implement, because of the lack of mould design tools. This project will develop a modelling program for mould-filling process, thus providing end-users with a computerized tool with which to resolve problems related to mould design. This will eliminate the prohibitive costs associated with trial-and-error design which have so far militated against the adoption of the resin-transfer process.
