摘要/Abstract

摘要： 通过试验研究挖补修理对平纹编织复合材料层合板静态拉伸与拉-拉疲劳性能的影响,疲劳试验应力比R为0.1。结果表明:挖补修理降低了层合板静态拉伸强度、静态拉伸模量、拉-拉疲劳极限和剩余载荷,挖补修理后恢复率分别为64.9%、82.5%、80.7%和76.6%;挖补修理层合板拉-拉疲劳寿命恢复程度随着载荷水平增加而减小;拟合的S-N曲线在有限寿命区具有较高可信度;经过10⁶次循环加载作用后的完好件和修理件的剩余载荷均小于静态拉伸破坏载荷,且循环加载后刚度均变大;所有试验件断口处均出现纤维断裂和基体开裂,完好件断口以纤维断裂为主,且伴有分层损伤,修理件断口补片与胶层之间发生剪切破坏导致补片与母板明显脱黏。

Abstract: The effects of scarf repairing on static tensile and tension-tension fatigue properties of plain woven composite laminates were studied experimentally, and the fatigue test stress ratio R was 0.1. The results show that the static tensile strength, static tensile modulus, tension-tension fatigue limit and residual load of laminates are reduced by scarf repairing, and the recovery rates are 64.9%, 82.5%, 80.7% and 76.6%, respectively. The recovery extent of tension-tension fatigue life decreases with the increase of load level. The fitted S-N curve has high reliability in the finite life region. After 10⁶ cyclic loading, the remaining loads of intact parts and repaired parts are both less than static tensile failure loads, and the corresponding stiffness increase. Fiber fracture and matrix cracking occur at the fractograph of all the test pieces. Fiber fracture is the main failure mode of the intact test pieces with the delamination damage. Shear failure occur between the patch and adhesive layer at the fractograph of the repaired test pieces, resulting in obvious debonding between the patch and the parent laminate.
