The mechanical and fracture behavior of polymer composites are the subject of great interest from many years and still interesting among the researchers. Composites are extremely used for their superior mechanical, thermal and fracture toughness properties in various sectors such as automobile, aerospace and defense applications. In this article, unidirectional and woven high strength glass, carbon and Kevlar fiber reinforced polymer textile composites are taken into consideration for the comprehensive review of mechanical behavior and fracture toughness characterization. Current review work began with the introduction to polymer textile composites with its manufacturing stages, processing techniques and factors affecting the performance under mechanical loading. The mechanical behavior of high strength fiber reinforced polymer (HSFRP) textile composites was discussed in tension, compression, flexural, low velocity and high velocity impact loading with the recent numerical and experimental characterization studies. Textile geometrical modeling and CAE tools are also described for numerical characterization. Under the influence of mechanical loading on composites, failure occurs actually due to the crack initiation and propagation, so it is also required to characterize. Significant elements of fracture mechanics are well described for the better understanding of fracture toughness characterization. Mode-I, Mode-II, Mode-III interlaminar and Mode-I intralaminar fracture toughness characterization are widely explained by considering the effect of filler content, fiber orientation and fiber volume fraction. Fracture toughness characterization techniques and research summery are uniquely presented by considering various factors under one umbrella for better understanding of fracture behavior. Statistical Weibull distribution is also presented for the failure prediction of composites.

多年来，聚合物复合材料的机械性能和断裂性能引起人们极大的兴趣，并且在研究人员中仍然很有趣。复合材料因其优异的机械，热和断裂韧性而在汽车，航空航天和国防等各个领域得到了极好的应用。在本文中，考虑了单向编织高强度玻璃纤维，碳纤维和凯夫拉尔纤维增强聚合物纺织复合材料的力学性能和断裂韧性表征。当前的审查工作从介绍聚合物纺织复合材料及其制造阶段，加工技术和影响机械载荷下性能的因素开始。通过最近的数值和实验表征研究，讨论了高强度纤维增强聚合物（HSFRP）纺织复合材料在拉伸，压缩，弯曲，低速和高速冲击载荷下的力学行为。还描述了纺织品几何建模和CAE工具以进行数值表征。在机械载荷对复合材料的影响下，断裂实际上是由于裂纹的萌生和扩展所致，因此也需要进行表征。为了更好地理解断裂韧性特征，对断裂力学的重要要素进行了很好的描述。通过考虑填料含量，纤维取向和纤维体积分数的影响，广泛解释了模式I，模式II，模式III的层间和模式I的层内断裂韧性。断裂韧性表征技术和研究综述是通过在一个保护伞下考虑各种因素来更好地理解断裂行为的唯一方法。统计威布尔分布也提出了复合材料的破坏预测。
