Abstract

In the present study, the buckling behavior of delaminated plate in woven fabric composite laminates was studied. For this purpose, at first, the structure of woven fabrics was defined as shape functions. Then, the continuous analysis was used to study the bucking of delaminated plates. Based on the Rayleigh–Ritz method, the related formulations were developed to predict the critical buckling load of composite laminates. Three types of woven fabrics (viz. Plain, Twill, and Satin architecture) were used as reinforcements for polyester composites. The 8-ply laminated composites were fabricated using Vacuum Infusion Process (VIP). The results of buckling test showed that the critical buckling loads of laminates reinforced with Plain, Twill, and Satin woven fabrics are 1.35, 1.12, and 1.48 kN, respectively. Also, the results of analytical method are compared with experimental results and those achieved by the finite element method of analysis using ABAQUS software. Compared with experimental results, the maximum error of analytical and FE models is about 17% and 10%, respectively.

玻璃纤维复合材料层合板中分层板屈曲行为的数值和实验研究

本文研究了机织复合材料层合板中分层板的屈曲行为。为此，首先将机织物的结构定义为形状函数。然后，采用连续分析方法对分层板的屈曲进行了研究。基于瑞利-里兹法，建立了复合材料层合板临界屈曲载荷的预测公式。三种机织织物(即平纹、斜纹和缎纹)被用作聚酯复合材料的增强材料。采用真空灌注法制备了8层复合材料。屈曲试验结果表明，平纹、斜纹和缎纹织物增强层合板的临界屈曲载荷分别为1.35、1.12和1.48 kN。并将分析方法的结果与实验结果以及利用ABAQUS软件进行有限元分析的结果进行了比较。与实验结果相比，分析模型和有限元模型的最大误差分别约为17%和10%。
