本文将单模光导纤维代替普通玻纤埋设于聚酯之中,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来测试埋设于聚酯之中光导纤维的各种应力应变情况(在复材受各种外力时),从而得到玻纤同聚酯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, single-mode optical fiber instead of ordinary glass embedded in 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 to test the optical fiber embedded in the polyester in a variety of stress and strain (in the complex material by a variety of external forces), to get the fiberglass with the interface of the micro-mechanical properties of the results, opened up a new Composite materials testing methods.
