本文将单模先导纤维代替普通玻璃纤维埋设于聚脂之中,将He-Ne激光分光后接入这一信号光纤及另一同样长度的参考光纤中,利用这两根光纤输出的激光的干涉效应采测试埋设于聚脂之中光导纤维的各种应力情况(在复合材料受各种外力时),从而得到玻璃纤维同聚脂的界面微观力学的各种结果,开拓了一种新的复合材料的测试方法. In this paper, a single-mode pilot fiber instead of ordinary glass fibers buried in the polyester, the He-Ne laser splitting access to the signal fiber and another reference fiber of the same length, the use of the two optical output laser interference Effect of mining test in the optical fiber embedded in the various stress conditions (when the composite material by a variety of external forces), resulting in the glass fiber with polyester interfacial micromechanics of the results, opened up a new complex Material testing methods.
