摘　　要：本文通过预应力法调整ＡＲＡＬＬ层板残余应力，研究了自由层板与两种预应力层板的Ｂｅｌｌ－剥离特性。结果表明，给层板施加预应力有效地降低了其中的残余应力，无论自由层板还是预应力层板，剥离所造成的断裂均为多重混合型破坏，其实质是芳纶／胶粘剂界面破坏和纤维自身的破坏，给芳纶施加预应力有利于Ｂｅｌｌ－剥离强度的提高，同时预应力的施加使剥离面上的纤维破坏状态发生改变。Applying pre-stress to the fiber/adhesive layer is adopted to modify the residual stress of ARALL, and the Bell-peel property influenced by different residual stresses in ARALL is investigated in this paper. The results indicate that the residual stress is lowered by applying prestress and no matter what kind of laminate, as-cured one or prestressed one, the fracture resulting from peeling is multiple. Imposing prestress on ARALL not only contributes to increase the Bell-peel strength, strength, but also changes the fracture state of fibers on the peeling surface.
