Due to superior material properties of fiber reinforced composites, they are utilized in many structural fabrications. Even though many studies have been reported about various fiber reinforced composites, it is indeed to find more eco-friendly composites for modern applications. So, developing the new fiber reinforced composites and revealing its mechanical properties are vital. In this examination, the natural fiber reinforced polymer matrix composite was prepared by compression molding method. The natural fiber named as Coccinia Indica was used to fabricate the fiber reinforced composites. The impact of different fiber length on dynamic mechanical properties like loss modulus, storage modulus, and loss of weight in fiber reinforced composites was predicted using dynamic mechanical analysis and thermogravimetric analysis. The outcomes revealed that fiber length of 30 mm shows better values in storage modulus and nominal loss modulus owing to higher interfacial bonding among fiber and matrix. However, in other fiber lengths, the storage modulus depicts poor result and high loss modulus is due to inefficient stress transfer.

籼稻纤维增强聚酯复合材料的动态力学和热特性试验研究

由于纤维增强复合材料的优异材料特性,它们被用于许多结构制造中。尽管已经报道了许多关于各种纤维增强复合材料的研究,但确实需要为现代应用找到更环保的复合材料。因此,开发新型纤维增强复合材料并揭示其机械性能至关重要。在本次测试中,天然纤维增强聚合物基复合材料是通过压缩成型方法制备的。名为 Coccinia Indica 的天然纤维用于制造纤维增强复合材料。使用动态力学分析和热重分析预测了不同纤维长度对纤维增强复合材料的动态力学性能如损耗模量、储能模量和重量损失的影响。结果表明,由于纤维和基体之间的界面结合程度更高,30 mm 的纤维长度在储能模量和标称损耗模量方面表现出更好的值。然而,在其他纤维长度中,储能模量表现出较差的结果,高损耗模量是由于低效的应力传递。
