Carbon fiber reinforced polymer composites have been developed into a key material which is massively applied in aerospace fields. Traditional autoclave curing technology exhibits serious problems, such as incapable curing large thickness and variable thickness carbon fiber composites components, long curing period and high energy consumptions. This project presents a method of carbon fiber reinforced polymer composites processed by high pressure assisted self-resistive heating, which is intended to reveal the curing mechanism of carbon fiber reinforced polymer composites self-resistive heating, research the change rule of carbon fiber composites electro-thermal characteristics influenced by different geometry size, layer direction, curing temperature, external pressure and electrode form, establish the self-resistive heated curing temperature field adaptive accurate control model for composite components. For the sake of providing theoretical and technical supports for the high quality, high efficiency and low energy consumption curing of carbon fiber reinforced polymer composite materials.
