摘　　要：对作为吸能元件的纤维增强复合材料圆柱壳的吸能特性进行了试验研究。制备了不同铺层角度和不同引发方式的玻璃纤维/聚酯树脂基圆柱壳,通过对该圆柱壳进行动态试验,探求铺层方式和引发方式对该吸能元件吸能效果的影响,以及该复合材料层合壳体压溃过程的破坏机理。In this paper, fiber-reinforced composite cylindrical shell as energy-absorbing components, it＇s absorption character istics were experimentally investigated. Composite cylindrical shells with different ply angles and different trigger modes of ini tiation made of glass fiber / polyester resin matrix were prepared, with the dynamic experiment on the cylindrical shells, car- ried out to seek the effects of ply angles and trigger modes on energy absorption, and laminated composite shell crushing failure mechanism of the process. It was found that, the effect of energy absorption of 70°, 75°,90°ply specimen were higher than 45°, 60°,ply specimen, and their failure mode is not the same. Compared with different trigger mode, the sharp corners and round ed trigger type have a better effect of energy absorption than chamfer angle trigger type, and they can greatly extend the re quired to crushed length which reaching the peak load. Above experimental findings may provide a reference for study and ap plication of this kind of composite material.
