摘要/Abstract

摘要： 本文利用有限元软件ANSYS,建立三维中空夹芯复合材料的结构模型,进行侧压性能研究。利用该模型,探讨了材料在1mm侧压位移载荷作用下复合材料中纤维、树脂和材料本身的应力、应变分布。结果表明,三维中空夹芯复合材料在侧压载荷作用下,上下面板中经、纬纱线交织处应力最大,最容易发生侧压破坏;芯材应力最小,不容易发生侧压破坏;复合材料在承受侧压载荷作用时,纤维起主要承载作用,树脂起次要作用;材料的破坏模式主要为树脂破裂。

Abstract: On the basis of previous studies, a new structural model was built to study compressive properties of three-dimensional hollow sandwich composites (3D composites) by using the finite element software ANSYS Workbench. The distribution of stress & strain on the fibers, resin and the 3D composites was discussed under compressive loads of 2 mm displacement by using the model. The results show that the maximum value of stress occured between the overlap of piles, where the 3D composites were damaged easily. The minimum value of stress occured on the up and down face-sheet, where the 3D composites were damaged difficultly. The main loads were supported by fibers and the minor loads were supported by resin. The main failure mode of the 3D composites are resin fracture when the 3D composites suffered compressive loads.

Key words: three-dimensional hollow sandwich composites, side compressive properties, finite element software ANSYS, stress, strain, failure mode
