Abstract: Previous simulations on composite curing process have some limitations,because they are usually performed either in the thickness direction of thick composite component or under a rather simple external environment.Therefore results of these simulations have some deviation from the actual composite curing process.Taking into considerations of factors such as auxiliaries,mold and forced convection phenomenon inside autoclave,refined simulation method is established on composite curing temperature field in autoclave technology.On this basis,curing temperature field simulations and results analysis with regard to composite structure and material system in aviation industry are performed.
