Abstract
In recent years, resin manufacturers have been formulating thermoset resins with a decrease in cure time. This has helped to shorten the process cycle times and paved the way for the use of cost-effective compression resin transfer moulding (CRTM) process to produce high performance composite parts. However, highly reactive resins pose a major challenge in producing high quality parts. Currently, many researchers have been working on the process simulation of CRTM process. However, there is still a large gap to be addressed in terms of coupling between heat transfer, cure kinetics, resin flow and compaction (thermal-chemical-mechanical) during the CRTM process especially for 3D structures. The main objective of this work is to perform thermal-chemical-mechanical coupled CRTM simulation for a flat 3D part. The work involved development of resin and fibre material models. The material models developed were implemented to perform the simulations. These simulations were validated using interrupted resin flow CRTM experiments.
