Abstract

Abstract: The temperature gradient of autoclave mold will increase the uncertainty of composite curing. Improving the uniformity of die surface temperature distribution can ensure the curing quality and forming accuracy of composite components. Most of the existing mold optimization schemes are difficult to operate and can not be applied to engineering practice. This paper proposes to add a straight plate with a certain angle along the flow direction as the guide plate in the mold support structure. By controlling the inclined angle of the guide plate and adjusting the compression degree of the gas at the back of the mold, the best position of the guide plate is finally determined. It can be used to guide the optimization of autoclave mold for composite components in practical engineering.

Key words: composite material, temperature field, mold, autoclave forming, structure optimization
