With excellent mechanical properties, carbon fibre–reinforced composites are widely used in many engineering structures. So many researchers have studied static failure feature of carbon fibre–reinforced composites, which could be influenced by ply angle,¹ environmental condition² and moulding technology.^3,4 With broad application of composites, composite structure is more and more complicated, and connection of different composite components becomes essential. Meanwhile, bolted joints are the most widely used in the composite components connection. With the development of composite technology, now composite has been applied in some primary and secondary load-bearing structures. For example, the central wing box of A350 is completely manufactured using composites. Usually, the composite primary load-bearing structure does not take fatigue into consideration due to the excellent fatigue property of composites or full-scale test of composite structure, which is time-consuming, expensive and over design. Therefore, to cut cost and improve reliability of whole service of composites, fatigue characteristic of composites has been considered critically important. Furthermore, study of fatigue of composite bolted joint becomes vital since composite bolted joint is the most common joint in structures.

使用等效应力模型进行复合材料螺栓接头渐进疲劳损伤分析

碳纤维增强复合材料具有优异的机械性能，广泛应用于许多工程结构中。许多研究人员研究了碳纤维增强复合材料的静态失效特征，该特征可能受到铺层角度、¹环境条件²和成型技术的影响。^3,4随着复合材料的广泛应用，复合材料结构越来越复杂，不同复合材料构件之间的连接变得至关重要。同时，螺栓连接在复合材料构件连接中应用最为广泛。随着复合材料技术的发展，目前复合材料已应用于一些主、次承重结构中。例如，A350的中央翼盒完全采用复合材料制造。通常，由于复合材料优异的疲劳性能或对复合材料结构进行全尺寸试验，复合材料主承载结构不考虑疲劳，耗时、昂贵且过度设计。因此，为了降低成本并提高复合材料整体使用的可靠性，复合材料的疲劳特性被认为至关重要。此外，由于复合材料螺栓接头是结构中最常见的接头，因此复合材料螺栓接头的疲劳研究变得至关重要。
