Abstract
At present, natural or lignocellulosic fiber-based bio composites are the talk of the town due to their low density, cost effective, eco-friendly, renewable properties. Bio fibers such as jute, kenaf, pineapple, sugarcane, flax, leaf, hemp, wool, silk etc obtained from plants or nature which can be utilized to obtain new high performance polymer composite materials. The physical and mechanical characteristics of these bio fibers (e.g., tensile properties, flexural stress-strain behaviour, fracture strength, impact strength) make them more sustainable and attractive than synthetic fibers with a remarkable biodegradable characteristic. The aim of this review is to give a thorough overview on natural fibers and natural fiber reinforced bio composite materials, their major physical and mechanical properties and potential applications.
Highlights
Nowadays, bio-composite materials are becoming more common as they are light weight, strong, cheap, biodegradable and sustainable
This paper focuses on the review of natural fiber and natural fiber-based reinforced biocomposites
It is related with banana family [45]. It has many advantages such as low density, appropriate stiffness, and mechanical properties and high disposability and renewability, recyclable and biodegradable. It is one of the strongest cellulose fibers which is used for marine applications, resistant to saltwater, commonly used for fishing nets, used for meat casings and abaca fiber is used in the production of the tea bags; utilize as a raw material and that raw material is used in the processing of high-quality paper, machinery filters, hospital textiles, electric conductor, etc. [8,46]
Summary
Bio-composite materials are becoming more common as they are light weight, strong, cheap, biodegradable and sustainable. Natural fibers used as an alternative reinforcement in polymer composites which has gained attention among many researchers and scientists due to their advantages over conventional synthetic materials [6] These natural fibers include jute, hemp, sisal, kenaf, coir, banana, bamboo, sugarcane, flax, and many others [7] which provide good mechanical properties compared to man-made fibers and they are reasonable, recyclable and renewable, reduce energy consumption, less health risk and nonabrasive to the equipment, non-irritation to the skin [8]. It can be used as a reinforced material because of its thermoplastic and thermosetting behavior. This study emphasizes on bio fibers, biocomposites, natural fiber-based reinforced biocomposites, physio-mechanical properties of fiber-reinforced biocomposites, globally current applications and addresses future developments of natural fiber-reinforced biocomposites
