Abstract Weave architecture of the reinforcement in polymeric composite structures affects macroscopic mechanical properties of the developed composites significantly along with many other factors. In present article, nine different but systematic weave architectures were obtained by changing the number of simultaneous yarns moving in warp and weft direction of flax (Linum usitatissimum) woven fabric. Static and dynamic mechanical properties (Tensile, Flexural, Impact, loss modulus, storage modulus and damping factor) of flax fiber reinforced epoxy composites were investigated. The effect of weave configurations on failure mechanism of the developed composites has also been studied morphologically. Scanning electron microscopy (SEM) was performed to investigate the failure mechanism of the developed composites. Tensile strength and modulus was found to be significantly affected by the number of simultaneous load sharing fibers weaved in loading direction and crimp of the fabric respectively. Interlacing points of the fabric seems to control the flexural strength and modulus of the developed composites. Reinforcement architecture was also found to be responsible for the changes in impact strength of developed composites. Consistent with Young’s modulus, storage modulus and loss modulus were also affected by weave parameters such as unevenness in the architecture of reinforcement.

增强结构对用于结构应用的亚麻/环氧树脂复合材料的静态和动态力学性能的影响

摘要 聚合物复合材料结构中增强材料的编织结构显着影响所开发复合材料的宏观力学性能以及许多其他因素。在本文中，通过改变在亚麻 (Linum usitatissimum) 机织物的经纬方向同时运动的纱线数量，获得了九种不同但系统的编织结构。研究了亚麻纤维增强环氧树脂复合材料的静态和动态机械性能（拉伸、弯曲、冲击、损耗模量、储能模量和阻尼系数）。还从形态学上研究了编织构型对所开发复合材料失效机制的影响。进行扫描电子显微镜 (SEM) 以研究开发的复合材料的失效机制。发现拉伸强度和模量分别受在负载方向和织物卷曲上同时编织的负载共享纤维数量的显着影响。织物的交织点似乎控制着开发的复合材料的弯曲强度和模量。还发现增强结构是开发复合材料冲击强度变化的原因。与杨氏模量一致，储能模量和损耗模量也受编织参数的影响，例如增强结构的不均匀性。还发现增强结构是开发复合材料冲击强度变化的原因。与杨氏模量一致，储能模量和损耗模量也受编织参数的影响，例如增强结构的不均匀性。还发现增强结构是开发复合材料冲击强度变化的原因。与杨氏模量一致，储能模量和损耗模量也受编织参数的影响，例如增强结构的不均匀性。
