摘要/Abstract

摘要： 树脂基复合材料成型过程中经常使用辅助材料来改善产品的质量、优化工艺过程,其中硅橡胶作为辅助加压材料,被大量应用于复合材料的固化炉、热压罐成型工艺中。硅橡胶具备高可塑性、耐温性等优点,在固化过程中能够稳定地对产品施加压力,保证产品表面及内部质量。通过对硅橡胶热膨胀加压及辅助传压等不同成型工艺过程的比较,进行了硅橡胶热膨胀加压工艺间隙的理论分析,系统地阐述了硅橡胶辅助加压工艺的实现过程,提出了温度、硅橡胶体积、模具间隙与固化压力之间的关系。

Abstract: The auxiliary materials are widely used in the forming process of composite materials in order to improve the quality of product and optimize the process. The silicon rubber, which is an auxiliary pressurizing material, is widely used in both curing oven and autoclave moulding process. Silicone rubber has the advantages of high plasticity and heat resistance. During the curing process, it can exert pressure on the product and ensure the surface and internal quality of the product. In this paper, the thermal expansion compression and auxiliary pressure transfer process of silicon rubber are compared, the theoretical analysis for the thermal expansion compression process gap of silicon rubber was carried out, and the realization process of silicon rubber assisted pressurization system is systematically expounded. Then, the relationship between the temperature, the volume of silicon rubber, the clearance of mould and the curing pressure is put forward. This relationship is verified through the design of the tooling and the manufacture of typical resin matrix composite products.

Key words: silicon rubber, pressure control, composite material, clearance
