Study on Simulation and Experimentation of H Wallboard for RTM Processing

Resin Transfer Molding(RTM)filling process of an H wallboard is simulated in 3D using the simula- tion system.This system was developed by Beijing University of Aeronautics and Astronautics independently. After analysis of the simulation results,the optimal injection way is set as center point injection and 8 reasona- ble vents are settled.Also,the effects of preform inhomogeneous permeability on RTM process are studied particularly.Mould manufacture and filling experiment are operated,the experiment results coincide with the simulation results basically.RTM process simulation gives veracious guidance to mould development and com- ponent manufacture.
