本文分析了单向复合材料板在剪切时的微观破坏过程，结合声发射技术监测其损伤的起始与扩展过程，确定了完整的τ-γ曲线上几个特定阶段。在不同损伤阶段，从不同方位切取断面，分别用微差干涉法与电镜法观察其微观破坏过程。

Unidirectional Composites micro failure process und er shearing was ana lyzed in this paper. The damage process from beginning to expanding was monitori ng with acoustic emission. Some special stages of the τ－γ curve was determine d In various damage stages the section that was cut in different direction was o bserved with differential interference method and electron microscope.
