An Integrated Manufacturing Process of CFRP Parts Based on RFI and Cutting Process

Due to the prominent mechanical and physical properties, CFRPs have a broad application prospects in many domains. Aiming to the problems faced by available machining processes of CFRPs, this work proposed an integrated manufacturing process of CFRP parts by combining RFI process with cutting process, which replaced machining processes of the difficult-to-machine CFRPs with cutting of the flexible carbon fiber fabrics infiltrated by melted resin matrix. And it carried out molding, cutting and curing in a press stroke by a multi-functional die whose structure is given in this paper. Furthermore, by comparing the cross-section quality of CFRP parts obtained from the proposed integrated manufacturing process with that of drilling, mechanical machining and laser cutting, the integrated manufacturing process is verified to be feasible, cost-effective and capable of avoiding subsequent machining processes of difficult-to-machine CFRPs.
