本文介绍了玻璃纤维编织层合板在低温循环载荷下的刚度退化和剩余强度的疲劳损伤行为的实验研究。在室温和低温下进行了单轴、载荷控制、拉-拉疲劳试验。应用应力与失效周期（S-N）的关系和疲劳极限的GFRP编织层压板和微裂纹的演变，由于疲劳载荷的特点是使用光学显微镜。还使用嵌入样品中心的热电偶测量温度。(C)2004爱思唯尔有限公司保留所有权利。
This paper describes an experimental study on the fatigue damage behavior of GFRP woven laminates in terms of stiffness degradation and residual strength under cyclic loading at low temperatures. Uniaxial, load-controlled, tension-tension fatigue tests were conducted at room and low temperatures. The applied stress versus cycles to failure (S-N) relationships and fatigue limits were obtained for the GFRP woven laminates and the microcrack evolution due to fatigue loading was characterized using optical microscopy. Temperatures were also measured using a thermocouple embedded in the center of the specimens. (C) 2004 Elsevier Ltd. All rights reserved.
