Thermal Properties of Natural Fiber Sisal Based Hybrid Composites – A Brief Review

ABSTRACT

Among natural fiber composites, sisal fiber is one of the promising reinforcement which provides enhanced mechanical strength to the composites. The sisal fibers are low cost, available at abundant, having low density, improved specific strength and modulus, and are nontoxic. It has been utilized by mankind from the olden period itself. These fibers were used for making mats, cloths, bags, hats, ropes, and many applications. The increased strength of sisal fiber attracted the design engineers in developing fiber composites. The sisal fiber reinforcement in composites proven to be an effective replacement for synthetic fibers. At present, sisal fiber composites have been found in vast engineering applications like automobile, railways, building materials, electrical industry, geotextiles, defense and in the packaging industry. To increase the sisal fiber composite, strength hybridization was introduced. Although several literatures explore the mechanical performance of the hybrid sisal composites, there is no proper literature that summarizes the thermal properties of the sisal hybrid composites. This review presents a summary of the thermal characteristics of hybrid sisal fiber composites.

摘要

在天然纤维复合材料中，剑麻纤维是一种很有前途的增强材料，它能提高复合材料的机械强度. 剑麻纤维成本低，原料丰富，密度低，比强度和模量提高，无毒. 它从远古时期就被人类所利用. 这些纤维被用于制造垫子、布、袋、帽子、绳索和许多应用. 剑麻纤维强度的提高吸引了设计工程师开发纤维复合材料. 剑麻纤维增强复合材料被证明是一种有效的替代合成纤维. 目前，剑麻纤维复合材料已广泛应用于汽车、铁路、建材、电气、土工布、国防、包装等领域. 为了提高剑麻纤维复合材料的强度，引入了杂交技术. 虽然已有文献对剑麻混杂复合材料的力学性能进行了研究，但目前还没有合适的文献对剑麻混杂复合材料的热性能进行综述. 本文综述了剑麻混杂纤维复合材料的热特性.
