摘　　要：为了研究高温环境下含有不同直径大小的孔的碳纤维增强复合材料层合板的屈曲性能与室温环境下的屈曲性能之间的差异,首先对纵向压缩载荷作用下碳纤维增强复合材料层合板的临界屈曲载荷的计算理论进行了分析并选定了用于衡量屈曲性能的指标——最小正特征值;随后,在商业化有限元软件ABAQUS中建立了一系列含有不同孔径大小的碳纤维增强复合材料层合板的有限元模型,并通过改变材料的性能参数来模拟碳纤维增强复合材料层合板所处的温度环境.ABAQUS软件的屈曲分析结果表明:高温环境会使得碳纤维增强复合材料层合板的屈曲性能有所下降,且随着孔径的增大,碳纤维增强复合材料层合板的屈曲性能降低得越快.In order to investigate the difference of buckling properties of the carbon fiber reinforced composite laminates with a series of holes whose diameters were different between in elevated temperature environment and in room temperature environment,the theory of calculating the critical buckling load of carbon fiber reinforced composite laminates under the longitudinal compression load was analyzed initially and an index which could describe the buckling properties was chosen,which was the minimum positive eigenvalue.Subsequently,a series of finite element models of carbon fiber reinforced composite laminates with different pore sizes were established in commercial finite element software ABAQUS.Through changing the performance parameters of the materials,the temperature environment of carbon fiber reinforced composite laminates were simulated.The buckling analysis results of ABAQUS software demonstrated that elevated temperature environment would cause the buckling properties of carbon fiber reinforced composite laminates to decrease,and with the increase of the diameters of the holes,the buckling properties of carbon fiber reinforced composite laminates decreased faster.
