摘　　要：由于用传统RTM工艺整体成型复杂结构复合材料构件有一定困难,所以用硅橡胶气囊模具代替RTM工艺中的金属阳模,并对这一工艺过程进行研究。通过硅橡胶力学性能试验,得出用硅橡胶的拉伸、撕裂、剥离强度等性能指标,可以满足气囊模具的要求。利用硅橡胶气囊辅助RTM工艺,可以制作纤维体积含量较高的复合材料构件。与其他模具相比,硅橡胶模具具有很多优点。研究表明,纤维体积含量随气囊内压力的增加而增加。Because it was difficult to manufacture the composite products with complex structure in a whole mold by traditional RTM, the silicon robber inflatable bag is used to replace the metal mold in the RTM process. Tested the mechanical properties of silicon mbber,tensile, tearing and peeing strength can are meet the demand of inflatable bag. The fiber volume of composite parts made by silicon robber inflatable bag is high. The silicon rubber inflatable bag has advantages over other molds. Studies indicate that the fiber volume of composites increased with the raising of pressure in inflatable bag. The relationship between pressure and fiber volume is not assured completely.
