| 摘 要： | 对碳纤维复合材料2种铺层的层合板进行了三点弯曲性能试验，分析了实验测试值．结果表明：从单向弯曲试验得到的拉伸强度值，通常高于从标准拉伸试验中得到的拉伸强度值；碳纤维层合板弯曲强度相对误差较小，合理的跨厚比是关键；弯曲试验方法只可用于质量控制，不适于数据设计；弯曲试验方法对其纤维方向与梁轴成0°或90°的层合板较适用．

| Abstract: | The test on three point anti-bending capability of two kinds of layer＇ s CFRP multi-plywood is carried out, and the test results are analyzed. The results show that the anti-bending intensity obtained from the unidirectional bend test usually is higher than which obtained from the standard tensile test;the bending intensity of carbon fibrous layer plywood relative error is small, and the reasonable cross thick ratio is a key; the bend testing method may only use in the quality control, which is not suitable for the data designing and the bend test method is suitable for 0° or 90° multi-plywood. |
