摘　　要：本文采用了Ｂｅｌｌ─剥离法研究了胶粘剂性质及其含量对ＡＲＡＬＬ层间剥离特性的影响。结果表明，层板的剥离过程为多重混合型破坏。由于芳纶／胶粘剂界面结合较差，其剥离强度值较低。使该界面脱粘而破坏，胶粘剂发生内聚破坏以及胶粘剂的韧性增大或含胶量提高均使剥离强度值提高。改善胶粘剂与芳纶的界面粘合状况、提高胶粘剂的韧性是提高层板层间性能的有效途径。it is adopted Bell-peel method to study the interlaminar property influenced by adhesive and its content in this paper. The result shows that the fracture of the laminate by peeling is multiple. Due to the weak interface of aramid/adhesive, the Bell-peel strength is lower. Intrinsic failure and higher toughness of the adhesive, as well as increasing the content of the adhesive in ARALL, enhance the value of Bell-peel strength of the laminate. Improving the interface of aramid/adhesive and toughness of the adhesive is the effective way to improve the interlaminar property of ARALL
