| Abstract: | Using the repair system that consists of 5-ethylidene-2-norbornene (ENB) and Grubbs catalyst as repair agent,and the hollow glass tube with the outer diameter 0.9 mm as the carrier of the repair agent,the bending performance and self-healing efficiency of the composite material contains hollow glass tube were examined by indentation test and three point bending experiments. As a result, the indentation test brings damage to the specimens up to a maximum of 14.67%.Meanwhile, the strength of the damaged specimens under the effect of repair system can restore to the original strength 99.15%. |
