In the present study, flax, jute and glass woven fabric samples were developed as reinforcement for composites with bio-epoxy resin. Flax fabrics were developed with plain weave, twill weave (different areal densities) and unidirectional (UD) structure. Jute fabrics were woven with three different structures i.e. plain, matt and twill respectively. For comparison purpose, glass woven fabric with plain weave and 3D orthogonal weave were used in this study. Static mechanical properties like flexural strength and impact resistance were studied. Dynamic mechanical properties were investigated by DMA 40XT RMI equipment.. Thermal conductivity has been studied for all composite samples. It is observed that the static mechanical properties of glass fabrics reinforced composites are superior but the flax & jute fabric reinforced composites are more flexible. The specific flexural strength as well as specific impact strength of the flax & jute fabric reinforced composites are competitive. The dynamic mechanical properties are comparable to that of glass fabric reinforced composites. They can be used in relatively lower load bearing applications as they are a sustainable source of materials for bio-composites which reduce the environmental burden and reduce the manufacturing cost.

天然纤维增强的生物复合材料:热,静态和动态机械性能的比较分析

在本研究中,开发了亚麻,黄麻和玻璃机织织物样品作为生物环氧树脂复合材料的增强材料。亚麻织物采用平纹,斜纹(不同的面密度)和单向(UD)结构进行开发。黄麻织物被编织成三种不同的结构,分别是平纹,哑光和斜纹。为了进行比较,在本研究中使用了具有平纹编织和3D正交编织的玻璃织物。研究了诸如弯曲强度和抗冲击性的静态机械性能。动态力学性能通过DMA 40XT RMI设备进行了研究。对所有复合材料样品的导热系数进行了研究。观察到,玻璃纤维增​​强复合材料的静态力学性能优异,但亚麻和 黄麻织物增强复合材料更具柔韧性。亚麻和黄麻织物增强复合材料的比抗弯强度和抗冲击强度具有竞争力。动态力学性能可与玻璃纤维增​​强复合材料相媲美。它们可用于相对较低的负荷应用,因为它们是生物复合材料的可持续材料来源,可减轻环境负担并降低制造成本。
