Buckling Analysis of Thin-walled Cylinder of Glass/Carbon Fiber Hybrid Composites Under Axial Pressure
摘要
Abstract
Thin-walled cylindrical structures were prone to buckling under axial compression.In this paper,the thin-walled cylinders made of glass/carbon fiber hybrid composites(G/CFHC)were taken as the object of study,six lay-up sequences were designed,and with the help of ABAQUS finite element analysis software,the effects of the position of the single-layer carbon fiber composite boards,the thickness of lay-ups,and the mixing ratio of the glass/carbon fibers on the buckling loads of the thin-walled cylinders made of G/CFHC were designed.The results show that under the same layup angle,the change of the position of the single-layer carbon fiber plate will lead to the change of the structural buckling load,and for the unidirectional layup of G/CFHC thin-walled cylinders,the influence on the buckling load is consistent,the maximum buckling load occurs in the single-layer carbon fiber plate located in the outermost layer,and the increase of the single-layer carbon fiber plate in the multi-directional layup even makes the structural buckling load decrease.For the different layup sequences of the thin-walled cylinders,the corresponding buckling load increases gradually with the increase of the layup thickness.When the thickness and the number of layers of the structure are certain,the increase of the single-layer carbon fiber composite and the reasonable change of the mixing method of the glass/carbon fibers will increase the buckling critical load of the structure and improve the stability of the structure.关键词
