LARGE-SCALE COMPOSITE CURING TEMPERATURE ANALYSIS AND IMPROVEMENT IN AUTOCLAVE PROCESS

Abstract

Abstract: The temperature field and flow distribution characteristics of the aero composite components in autoclave process, which based on the Fluent fluid analysis software, have been given in this paper. This work gives a method of fan installed on the frame type mold ventilation hole to enhance the thermal convection of air, and improve the uniformity of temperature field and flow distribution. The results show that, the flow field behind of frame type mold surface is complex, which has a flow vortex. Besides, the contact surface of composite has low temperature. However, the reasonable arrangement of fan position and control velocity can change the flow field inside the autoclave, make temperature uniformity of mold surface, and it is important to improve the curing temperature distribution uniformity of composite structure.

Key words: composite material, flow field, temperature field, uniformity, simulation
