Study on Resin Infusion Behavior of the CFRP Integrated Manufacturing Process Based on RFI Process

Abstract:

In the CFRP integrated manufacturing process based on RFI process, a CFRP stacking sheet is fabricated by laying alternatively Carbon Fiber Fabrics on Epoxy Resin Films each other. So its infusion process can be regarded as a concurrent infusion system consisting of some representative infusion systems with the delay time. Where, each representative infusion system includes a single layer resin film and a single layer carbon fiber fabric. It means that the infusion behavior of a CFRP stacking sheet can be described as a combination of the time delay from the bottom layer to the top layer and the required infusion time of the top representative infusion system. Based on this idea, the infusion behavior of the CFRP stacking sheets with different infusion pressures and the number of layer of Carbon Fiber Fabric is researched with the aid of the simulation software of RFI process developed especially and experiments, whose objects is to discover the impacts of the number of layer of Carbon Fiber Fabric and the infusion pressure on the resin infusion behavior. It is noticed that the predicted results have a good agreement with the experimental ones, which also verifies the applied method in this paper is feasible and valid to determine proper process conditions of the CFRP integrated manufacturing process.
