Quality of CFRP Cross-Sections by Cutting at the Situation of Resin Infiltration and their Defects Suppressing

Abstract:

As a kind of promising lightweight material, CFRP (Carbon Fiber Reinforcement Polymers) have been widely concerned in automobile industry in last decades. In the present work, series of experiments are conducted to investigate the impact of key process conditions, including the cutting edge geometry, curing process and cutting manner, on the CFRP cross-sections quality by cutting at resin infiltration during implementing the CFRP parts integrated manufacturing processes based on RFI process. For the typical cross-section defect such as the debunching of carbon fiber, chippings of carbon fiber and resin salivation, authors explain why that happens and propose the corresponding suppressing measures. Research results show that, under the existing experimental conditions, the optimal process scheme is to combine the large arc edge with curing before punch returns back and press cutting to obtain the desired CFRP cross-sections.
