Abstract：

A new composite molding process of “forming-cutting-curing” was presented and a composite forming device consisted of compound die for forming and blanking, heating unit and temperature-controlling unit was designed for CFRP materials based on RFI process. With the device, the integrated manufacturing of CFRF blanking parts was successfully implemented, and the cross section of a CFRP blanking part was smooth and flat, meanwhile it conquered the disfigurements such as filament winding, pull-out of the fiber and delamination while drilling and milling. Furthermore, the device can provide the specimens for tensile test, compression test, bending test, shear test and torsional test for the study of mechanical properties of large CFRP structures manufactured by RFI process and the necessary support for researching the optimized process solutions and quality control measures applied to the manufacture of large CFRP structures.
