摘要
对树脂传递模塑用M-3193不饱和聚酯进行了系统的研究,分析了温度、边缘效应以及S iC纳米粉填料对树脂流动性和材料力学性能的影响。结果表明,该体系在80℃以上存在低于60mPa.s的低粘度平台,满足RTM工艺对树脂粘度的要求;较大的边缘效应导致树脂在预制体内流动不充分,复合材料强度降低;添加S iC填料使材料的硬度提高了30%,而对材料的强度影响不大。通过对预制体进行真空浸渍前处理,提高了复合材料的强度,测得的材料弯曲强度达到325MPa。
In this paper the processing property of M-3193 unsaturated polyester resin for Resin Transfer Molding is studied systematically. The effect of temperature, edge effect and SiC nm filler on resin liquidity and mechanical property of materials is analyzed. It is demonstrated that system of M-3193 unsaturated polyester resin maintains a viscosity well under 60mPa · s when the temperature is above 80℃ and large edge effect induces resin flow inadequate in fiber bundle, which reduced strength of composites. Besides, the hardness of composites increased 30% , and the strength of composites have no change when SiC nm filler is added. In another hand, the strength of composites is enhanced when perform is vacuum impregnated, the flexural strength of composites reach 325MPa.
