A Review on the Sustainability Prospects of Bio Fibre Reinforced Composite Materials

Abstract

AbstractA bio composite is a material composed of a matrix (resin) and natural fibre reinforcement. Environmental concerns as well as the exorbitant costs of synthetic fibres sparked the development of natural fibre reinforcement in polymer composite. The concept of using green materials has become more popular over the last decade. With heightened awareness of the importance of environmental preservation, sincere efforts can indeed be cited all over the world in the search for biodegradable and bio-based sources. Bio composites have the proclivity to absorb dampness via the interface, matrix, reinforcement and the zones already adversely impacted by the formation of pores, cracks and delamination of layers. Due to the positive uses of bio fibre materials, many researchers have been obligated to investigate the potential use of natural fibres as reinforcement in bio composites. Due to the mechanical qualities, low density, environmental benefits, renewability, and commercial viability, cellulosic fibres are becoming increasingly tempting for the creation of bio-based products. Natural fibre polymer composites have recently acquired popularity for a variety of industrial applications due to the relatively low density and renewability. The main key factors in the research and development of bio composites are the hazards of synthetic fibres, recycling issues, and toxic by-products. Bio composites are environmentally friendly, renewable, non-abrasive, and non-toxic, with characteristics equivalent to synthetic fibre composites and used in a broad array of applications. Due to the above-mentioned merits, developing nations are increasingly turning to new green materials, including natural fibres, to help meet the demands of weight reduction, environmental concerns, and customer satisfaction. Nevertheless, effectively replacing green bio composites presents multiple barriers. The most daunting barrier in this field is the lack of data on the effectiveness of biocomposites characterized by a wide range of constituents. This article outlines the challenges in the development of bio composites towards sustainability.KeywordsBio fibresBio compositesSustainabilityNatural fibreBiodegradability
