This paper presents the experimental self-healing investigations on fiber-reinforced polymer (FRP) composites using a novel in-situ healing approach. During the preparation of polymer composites, the monomer Dicyclopentadiene (DCPD) was embedded as the healing agent. The compartment hollow glass microcapillaries were used to serve the localized distribution of the healing agent. To determine the viability of the proposed microcapillary approach, several flexural tests were conducted to initiate the damage and subsequent realization of self-repair activity. The healing was initiated through the polymerization of DCPD in the presence of Grubb’s catalyst (first and second generation). Once healed, the specimens were tested cyclically to evaluate the recovery of flexural strength. A post-failure healing efficiency as high as 72% has been observed. SEM and XRD investigations have been conducted for the microstructural investigations. These investigations support the potential applications of the proposed concept of embedding the bulk with the microcapillaries.

本文介绍了使用新型原位愈合方法对纤维增强聚合物（FRP）复合材料进行的实验性自愈研究。在聚合物复合材料的制备过程中，嵌入了单体双环戊二烯（DCPD）作为治疗剂。隔室中空玻璃微毛细管用于治疗剂的局部分布。为了确定所提出的微毛细管方法的可行性，进行了几次弯曲试验以引发损伤并随后实现自我修复活动。在格鲁布催化剂（第一代和第二代）存在下，通过DCPD的聚合反应开始愈合。愈合后，将对样品进行周期性测试以评估其抗弯强度的恢复。观察到故障后的治愈率高达72％。SEM和XRD研究已经进行了显微组织研究。这些研究支持将主体与微毛细管嵌入的拟议概念的潜在应用。
