STUDY ON SILICON RUBBER ASSISTED PRESSURIZATION EXTRUSION MOLDINGPROCESS OF RESIN MATRIX COMPOSITE

Abstract

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
