摘要
在这项研究中,我们通过实验研究了配件的形状如何影响拉挤玻璃/环氧树脂复合材料框架中斜接缝的承载能力。具体来说,我们使用了燕尾形(D 形)、H 形和矩形(U 形)三种钢制配件来加固复合材料框架中的斜接缝。为评估这些接头配置的承载能力,进行了拉伸和压缩试验。此外,我们还采用了有限元分析(FEA)来研究接头配置内的应力分布模式,从而对接头配置的强度进行比较。研究结果表明,无论在拉伸还是压缩加载条件下,所有类型的接头配置都能成功提高接头强度。值得注意的是,与 U 型钢制接头相比,H 型和 D 型钢制接头在加强粘合剂斜接接头方面表现出更高的有效性,尤其是在拉伸加载情况下。此外,所有类型的钢接头都有望成为在压缩载荷情况下增强接头强度的可行选择。
Enhancement of mechanical strength of miter joints in pultruded fiberglass/epoxy composite
In this research, we experimentally investigated how the shape of fittings affects the load-carrying capacity of miter joints in pultruded glass/epoxy composite frames. Specifically, three types of steel fittings – dovetail (D-shaped), H-shaped, and rectangular (U-shaped) were utilized to reinforce the miter joints in composite frames. Tension and compression tests were performed to assess the load-carrying capacity of these joint configurations. Additionally, finite element analysis (FEA) was employed to examine stress distribution patterns within the joint configurations, allowing us to make comparisons among the joint configurations in terms of their strength. The findings of the study demonstrated that all types of joint configurations successfully improved the joint strength, regardless of whether they were subjected to tensile or compressive loading conditions. Notably, H and D type steel fittings exhibited superior effectiveness in strengthening the adhesive miter joints when compared to U type steel fittings, particularly in tensile loading scenarios. Moreover, all types of steel fittings displayed promise as viable options for enhancing joint strength in compressive loading situations.
