【Abstract】 Bolted joints offer advantages such as stable load transfer and the ability for repeated disassembly and reassembly, becoming the main connection mode for polymer matrix composite structural components. The connection region is the critical weak point in component strength and reliability, determining the load-bearing capacity of the entire structure. Aiming at the bolted joints between two thermoset laminates, between laminate and metal plate, and between two thermoplastic laminates, the latest research progress is reviewed in several respects, such as the degradation process of performances, damage mechanisms and failure modes. The effects of various factors on both the strength and stiffness of the joint are summarized quantitatively. The factors include both the material properties and thickness of the laminate, the thickness and layup angle of prepreg, fiber content, overlap dimensions, bolt hole positions, the stiffness of metal plates, and so on. References are provided for reliability evaluation of composite components with bolted joints. Finally, the future research direction of bolted polymer matrix composites is envisioned in terms of improving the scientific design and strengthening the guidance of practical engineering.更多还原
