本文介绍了各种纤维增强聚合物（FRP）复合材料，即碳，玻璃，聚对苯撑苯并二恶唑（PBO），玄武岩纤维的疲劳行为，包括混合应用，如碳/玻璃和碳/玄武岩复合材料的效果。进行了一个试样试验，以检查在单调和循环载荷下的FRP复合材料的力学特性。测试参数包括施加的负载范围和不同类型的杂交。研究结果表明：（1）PBO纤维和玄武岩纤维的力学性能与传统的碳纤维和玻璃纤维相当，（2）纤维的拉伸模量影响复合材料试样的破坏模式，（3）复合材料的疲劳破坏是由损伤的渐进扩展引起的，（4）纤维的拉伸模量对复合材料试样的疲劳破坏有重要影响。（4）与均质玄武岩复合材料相比，碳/玄武岩混杂复合材料显著提高了抗疲劳性，而碳/玻璃混杂复合材料的抗疲劳性没有提供这样的效果。(C)2010爱思唯尔有限公司版权所有。
This paper presents the fatigue behaviour of various fibre reinforced polymer (FRP) composites, namely, carbon, glass, polyparaphenylenl benzobisoxazole (PBO), and basalt fibres, including the effect of hybrid applications such as carbon/glass and carbon/basalt composites. A coupon test was conducted to examine the mechanical characteristics of the FRP composites subjected to monotonic and cyclic loads. Test parameters included the applied load range and different types of hybridization. Study results show that (1) the mechanical properties of the emerging PBO and basalt fibres are comparable to those of the conventional carbon and glass fibres; (2) the tensile modulus of the fibres influences the failure mode of the composite coupons; (3) the progressive damage propagation causes fatigue failure of the composites; (4) the hybrid composites of carbon/basalt significantly improves the fatigue resistance in comparison to the homogeneous basalt composite, whereas the resistance of the carbon/glass hybrid composites does not provide such effects.
