The die for composite is the basis of the manufacture, and the technique of Rubber Pressure Die is important for Integrated-Solidification of the composite. We can call Rubber Pressure Die as Flexible Die. It is easy to transform to be fitting with the composite component, and it is credible for transmission of pressure, so it’s used in Integrated-Solidification of the composite widespread. According to the actual needs of project, the composite is putted into rubber as reinforced layer to enhance the stiffness and stability, so it not only has some stiffness, but also be fitting with the component well. But actually the stiffness value of Flexible Die is made by the experience in the fabricating process. So far there is no effectual analysis method for the effect of the Flexible Die structure on the pressure transmission, and also no direction for the Flexible Die stiffness design, which is rudderless in the actual project.For the actual problem, the research contents are mainly described as the follows:Firstly, the modulus of Flexible Die is tested, and the effect of reinforced layer number and thermal cycle time on the Flexible Die stiffness is investigated. Because of the rubber in Flexible Die is non-linear, the constitutive equations is created, and its parameter is calculated for finite-element method.Secondly, the Flexible Die stiffness forecasting is created, that investigates the effect of the stiffness of reinforced layer, the thickness of reinforced layer, and the thickness of rubber on the Flexible Die stiffness, that create the instruction of how to design the Flexible Die stiffness.Finally, the effect of the stiffness of reinforced layer, the thickness of reinforced layer, the thickness of rubber, the configuration of Flexible Die, the distribution of reinforced layer, the radius of the composite component on the uniformity coefficient of pressure transmission, that is the instruction for Flexible Die in the project.
