It is recognized that the uniformity of mould temperature fields during the composite curing process has a vital important effect on the component and, thereby, the product quality. Previous studies mainly considered the temperature along the thickness direction of the mould or composite component, or under a rather simple external environment, leading to some deviations from the actual composite autoclave curing process. In this paper, taking into consideration some factors such as auxiliaries, framed mould and forced convection phenomenon inside an autoclave, a simulation model has been established on the mould curing temperature field in an autoclave. On this basis, simulation and thermal analysis of the framed mould temperature fields with regard to composite structure and material system in the aviation industry have been performed. Besides, the influences of the time of heat preservation, heating rate have been also investigated, and two nondimensional factors are introduced for evaluating temperature uniformity and heating quality. It is found that increasing the time of heat preservation and the number of periods could improve the uniformity significantly, and, thus, the improvements of heating efficiency and uniformity of temperature field are achieved, and that a smaller heating rate would give much better heating quality.
