[Abstract]:In order to study the influence of composite adhesive overlay on joint strength, single lap joint is taken as the research object. The adhesive of the joint has the same tensile modulus and bending modulus through the ply design, but the ply angle of the adhesive surface is different, and the joint has the same tensile modulus and bending modulus, but the bonding joint has the same tensile modulus and bending modulus, but the ply angle is different. In this paper, the finite element method is used to model the joints of different layers, and the stress of the bonding surface and the adhesive layer are analyzed. The Tsai-Wu failure factor is introduced to evaluate the bonding layer. The results show that the angle of the bonding surface has a certain effect on the stress distribution. The 0 擄bonding surface will result in a larger adhesive layer stress, but the stress and failure factor of the adhesive surface are relatively small. The stress of adhesive layer under 90 擄layer is the least, but the stress and failure factor level of adhesive interface is higher, and the failure factor and layer stress level of adhesive interface at 45 擄is between them. Through the comparison with the experimental results, the general law of the influence of the angle of the adhesive overlay on the strength and failure mode of the joint is obtained.
