Abstract

Microwave curing has been deemed to be a rapid and cost-effective technology for curing carbon fiber-reinforced composite. In this study, a set of devices about high-pressure microwave curing were built with a real-time temperature measurement and control system of microwave input. Under a given high-pressure microwave curing process, different heating rates were applied to the carbon fiber-reinforced plastic (CFRP) laminates. The effect of heating rate on the curing quality was studied by interlaminar shear strength (ILSS), the void content of composite samples was observed by optical digital microscope(ODM) and the fracture surface of composite samples in these tests was inspected by scanning electron microscope (SEM). The results showed that the heating rate had a significant effect on the ILSS of CFRP laminates. The ILSS of CFRP laminates decreased and the void content increased with the increasing heating rate under high-pressure microwave curing. There were a large amount of hackles among carbon fibers when the heating rate was less than 6 °C/min. When the heating rate was 6 °C/min under high-pressure microwave curing process, the total time could be saved 28.85%, and the ILSS of sample was basically consistent with the value of sample in standard thermal curing.
