摘　　要：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 article, a single-mode optical fibre is used instead of an ordinary fibre to be covered up with polyester. When the He-Ne laser light goes through the single-mode optical fibre and the reference optical fibre of the same length, we could test the stress and strain in the optical fibre in composites from the interference of the two beams of light,, Then we could get many results about the interface micro-mechanics in composites .This article has developed a new sensitive test method about composites.
