In this paper, the shear deformation behavior in the interface between the plastic and the fiber is described. we tried two load type test by using the boron fiber embedded in a plastic resin which had diameter 14mm. One is the pull out test method and another is the push out one. The main conclusion obtained by the present study is shown as follows. The relationship between the shearing force and the shearing deformation has the velocity dependence. The separate fracture of the interface begins by the maximum shearing load. The difference of the test method doesn't influence the maximum shearing force. It was found that the main bond strength between the fiber and the plastic resin was the dynamic friction force.By the way, the mean shearing stress depend on the thickness of the specimen. It is thought that this cause is related to an interfacial stress distribution. Therefore, we tried to analyze the internal stress of the plastic resin which had the thickness from 1 to 6 mm and diameter 14mm by using FEM. It was found that the shearing and the radial stress had the maximum values on the top of the specimen. However, the two stresses couldn't explain the relationship between the mean shearing stress and the thickness. It is an important problem to find an appropriate stress at the separate fracture of the interface.

本文描述了纤维与塑料界面的剪切变形行为。我们使用嵌入直径为14 mm的塑料树脂中的硼纤维尝试了两种载荷类型测试。一种是拔出试验方法，另一种是推出试验方法。本研究得出的主要结论如下。剪切力和剪切变形之间的关系具有速度依赖性。界面的分离断裂开始于最大剪切载荷。试验方法的不同对最大剪切力的影响不大。结果表明，动态摩擦力是影响纤维与树脂粘结强度的主要因素，而平均剪切应力与试件厚度有关。据认为，这一原因与界面应力分布有关。因此，我们尝试用有限元法分析厚度为1 - 6 mm，直径为14 mm的塑料树脂的内应力。结果表明，剪切应力和径向应力在试样顶部有最大值。但这两种应力不能解释平均剪应力与厚度的关系。在界面分离断裂处寻找合适的应力是一个重要的问题。
