Sensitivity Analysis of Influencing Factors on Mould Surface Deformation of Resin Matrix Composites by Autoclave Moulding

In this paper, the reasonable determination of mould design parameters for the autoclave moulding method of fiber reinforced resin matrix composites is discussed. By comparing the influence of two design parameters of mould surface thickness and ventilation opening rate on the mould surface deformation in the working process, it is concluded that the influence of increasing the mould surface thickness on the mould working deformation is greater than that of reducing the ventilation opening rate on the mould deformation. In order to ensure the required rigidity of the mould, sufficient mould surface thickness should be designed.
