摘　　要：通过融熔缩聚法合成出一种低成本的不饱和聚酯酰胺脲树脂并表征了其性能。以此为基体,聚磷酸钙纤维(CPPF)为增强体,引入一定量的交联剂和引发-促进剂经室温交联后再在一定温度深度交联成可完全降解的CPPF/不饱和聚酯酰胺脲树脂复合材料,研究了其物理力学和降解性能。结果表明,合成的基体树脂中加入20%交联剂室温预交联再热处理后复合材料具有较高的力学强度;当CPPF的质量分数超过60%时,复合材料的力学强度出现下降的趋势,降解3个月后,含30%CPPF和50%CPPF的复合材料的弯曲强度分别能保持143MPa和148MPa。The low cost unsaturated poly（ester-amide） urea resin was synthesized by melt polycondensation and its performance was characterized. Calcium polyphosphate fiber （CPPF） was introduced to reinforce unsaturated poly （ester-amide） urea resin, and completely degraded CPPF/unsaturated poly（ester-amide） urea resin composites were prepared by adding a certain amount of crosslinking agent and initiator-accelerant agent at room temperature. Its mechanical performance and degradation properties were studied. The results show that the matrix resin crosslinked with 20% cross-linking agent at room temperature has high mechanical strength after heat treatment. As CPPF content exceeds 60% composites with 30 % , the mechanical strength of the composites decreases. After 3 months , the bending strength of and 50 % CPPF still maintain 143MPa and 148MPa respectively.
