Modeling of the vacuum assisted resin transfer molding process

Paper in proceeding, 2019

The vacuum assisted resin transfer molding (VARTM) process is widely used for producing large-scale and thin-walled fiber reinforced polymer composite materials. The resin flow movement and the fiber preform deformation essentially affect the quality of the final products. To predict and simulate those facts, we treat the resin flow as in-plain flow and allow the preform deform only along the normal direction. So that, instead of using expensive 3-D models, the present 2-D model is developed and can be applied to predict the VARTM process for large-scale and thin-walled composite products.
