| 摘 要： | 分析了CaCO3填料的添加量对不饱和聚酯树脂（UPR）浇铸体拉伸强度的影响，采用应变片电测技术考察了CaCO3含量对其固化过程的影响作用并对固化内应力进行了粗略的计算与分析。结果表明：填料CaCO3的添加量对不饱和聚酯树脂固化应变有显著的影响；填料CaCO3提高不饱和聚酯树脂拉伸强度的原因之一是其降低了浇铸体中固化内应力。

| Abstract: | By means of strain gauges,the effect of CaCO_3 addition on the inner stress during curing procedure of unsaturated polyester resin(UPR) was studied in this paper.In order to investigate the effect of filler addition how to influence the tensile strength of UPR specimen with CaCO_3 is involved.The experimental results showed that one of the main reasons improving the tensile strength of UPR is due to decrease the inner stress evidently and the curing strain of the UPR is dependent on the addition of the filler. |
