Impact, Hardness and Water Absorption Properties of Natural Fibres (Banana, Hemp and Sisal) Hybrid Composite Material

Abstract

Modern composite materials constitute a significant proportion of the engineered materials market ranging from everyday products to sophisticated niche applications. While composites have already proven their worth as weight-saving materials, the current challenge is to make them cost effective. The natural origin of these materials causes, in general, a wide range of variations in properties depending mainly on the harvesting location and conditions, making it difficult to select the appropriate fibre for specific applications. Natural fibres as effectively as possible to produce good quality fibre- reinforced polymer composites forvarrious engineering applications .In the experiments of tensile, flexural and impact tests were carried out for sisal, fibre hemp fibre hybrid- reinforced epoxy composites. And it able to replace the synthetic fibres that it has the eminent benefits of like low density, small manufacturing cost, its availability, ease of manufacture, low development energy, non-abrasive, worthy acoustic proper biodegradability, reasonable mechanical strength, renewability. Composite were made-up by hand lay-up method with the bidirectional natural fibres and epoxy resin in a mould and cured under gradual pressure. In this research paper mechanical behaviour such as tensile, flexural, indentation capacity and reinforced hybrid composite materials (BHSHC) studied. The purpose of this work to investigate, the mechanical characterization of the hybrid composite material. Sample was prepared and tested accordance to the ASTM standards. Characterization of hemp fibres was carried out with fibres obtained with low handling damage and deliberation damage to get an indication of how strong cellulose based fibres that can be produced from hemp.
