胶接面纤维铺层角度对复合材料胶接应力和强度影响分析
|
摘要
为研究复合材料胶接面铺层对接头强度的影响,以单搭接接头为研究对象,通过铺层设计使接头的被粘物具有相同的拉伸模量和弯曲模量,但胶接面的铺层角度不同,使用有限元法对不同铺层的接头进行建模,分析接头胶接面和胶层的应力,引入Tsai-Wu失效因子对胶接面铺层进行评估。结果表明:胶接面铺层角度对应力分布有一定影响,0°胶接面会造成较大的胶层应力,但胶接面的应力和失效因子较小;90°铺层下胶层应力最小,但胶接面的应力和失效因子水平较高;45°下胶接面的失效因子和胶层应力水平介于两者之间。通过与实验结果对比,得出了胶接面铺层角度影响接头强度及破坏模式的一般性规律。
To study the relations between joint failure force and ply angle of Ply Adjacent to Adhesive Layer( PAAL),designed a series of single-lap joints with same tensile modulus and bending modulus adherends but different orientation angles of PAAL,to analysis the effects of PAAL on stress distribution,using Finite Element Method( FEM) to model the adhesively bonded composite single-lap joints with different stacking sequences,stresses of adhesive layer and PAAL were analyzed,and introduced a failure index with Tsai-Wu failure criterion to compare the failure level of PAALs. The result shows the ply orientation of PAAL cause stress variation,with 0°,the stress of adhesive layer is highest,when the stress and failure index of PAAL is lowest; with 90°,the stress of adhesive layer is lowest,when the stress and failure index of PAAL is highest; the stress level of adhesive layer and failure index level of PAAL with 45° are between the results of 0° and 90°. A common rule was achieved by comparing the result and experiments data.
