玻/碳混杂纤维复合材料加筋板的屈曲和后屈曲分析
Buckling and post-buckling analysis of glass/carbon hybrid fiber composite stiffened plates
摘要
Abstract
The glass/carbon hybrid fiber composite reinforced panel was studied.The buckling load and ultimate bearing capacity of the stiffened plates are calculated by the finite element software ABAQUS,and the effects of re-inforcement section form,number of reinforcements and size of reinforcements on the buckling load of the composite stiffened plates are discussed,and the load-displacement curves of the structure and the damage failure modes during post-buckling arestudied.The results show that the I-shaped reinforcement method is better than the J-shaped and T-shaped reinforcement methods.The buckling resistance of the glass/carbon fiber sandwich composite reinforced panel is better than that of the interlayer hybrid composite reinforced panel under the same reinforcement method.The buckling load of the structure increases with increasing the number of reinforcement bars in all three reinforce-ment methods,and the lifting efficiency is the highest when the number of reinforcement bars is 3;the height of 10 mm has the highest efficiency for the buckling resistance of the structure,while the width of the upper edge and the width of the lower edge have less influence on the buckling load.In addition,the failure modes of post-buckling are mainly of tensile damage failure of the matrix and compressive damage failure of fibers,and the damage area and trend are mainly related to the laying angle and laying sequenc of fibers.关键词
