The Research on RTM Molding Process of Thin-wall Rib Structure of Composite Materials

摘要

The numerical simulation of RIM process is vital for mould design, control of process and parameters optimization and is the important method lowering development costs and ensuring quality. The paper conducts a finite element classification to the rib structure products with 65% fiber volume and the thickness of 1.5mm, conducts an emulation calculation to rib products with PAM-RTM software, provides frontier line of resin flowing at different time, calculates gridding and the distribution of pressure field at ending time, determines the positions of glue entering and vent hole and finally conducts a physical verification.
