摘　　要：介绍了一种用于复合材料板试样作双向加载试验的材料试验机,该试验机由计算机控制,可实现按比例的双向加载,可在4个应力象限內作不同形式的组合应力试验,最大拉伸载荷可达110kN,最大压缩栽荷可达170kN。该试验机的研制成功为复合材料强度理论的研究提供了有利的条件。A bidirectional loading testing machnie for composite plate specimens is intro- duced in this paper.The testing machine is cantrolled by a computer.It can realize bidirectional loading in proportion and do different types of combined stress tests in the four stress quadrants,with the maximum tensile load up to 110kN,the maximum compressive load up to 170kN.The successful development of the testing machine is of benifit to the theoretical study in composite strength.
