With the development of combat efficiency ratio of military aircraft and fuel economy of civil aircraft

carbon fiber reinforced polymer composites with low density and high strength are widely used in aircraft. Composites molding tooling should be reduced in the use of support blocks

and the use of Invar steel manufacturing tooling improves the manufacturing accuracy of composite components. Low curing pressure during forming the composite member can cause internal defects in the composite member. Low heating rate and cooling rate can reduce the influence of temperature gradient on the deformation of the composite member. Bowl-shaped parts are precisely manufactured by compensating tooling and molding optimization of process parameters.
