热膨胀硅橡胶是复合材料热膨胀模塑法成型中作为膨胀模使用的关键材料。 根据热膨胀模塑的原理,很多弹性材料都是可以充当膨胀模使用的。但是,目前研究较成熟且应用较多的是有机硅橡胶。有机硅橡胶作为热膨胀模使用,有其独特的优点。所以,重视复合材料热膨胀模塑技术的美国、法国和西德,都有自己的专用于热膨模塑技术的热膨胀硅橡胶,美国已有这类橡胶的系列牌号。 硅橡胶能浇铸、压延和挤压成复杂的形状,而且其尺寸稳定性好,所以是理想的模具
Thermal Expansion Silicone rubber is a key material used as an expansion mold in the molding of composite thermal expansion molding. According to the principle of thermal expansion molding, many elastic materials can be used as expansion molds. However, the more mature and applied research is silicone rubber. Silicone rubber as a thermal expansion mode use, has its unique advantages. Therefore, the United States, France and West Germany, which attach importance to the thermal expansion molding of composite materials, have their own thermal expansion silicone rubber, which is specially used for thermal expansion molding technology. The United States has such series of rubber grades. Silicone rubber can be cast, calendered and extruded into complex shapes, and its dimensional stability, it is the ideal mold
