Investigation of the properties and weathering behaviour of arecanut sheath fibre reinforced epoxy composites

Abstract

ABSTRACT Engineered materials having unique elements such as reinforcing phases and matrix materials, such as composites, provide improved stiffness, strength, lightweight characteristics, and corrosion resistance. The utilisation of natural fibre composites, which are derived from sustainable resources such as areca nut sheath, is on the rise because of their affordability, favourable strength-to-weight ratio, and lightweight characteristics. These composites offer a more environmentally friendly option to traditional synthetic fibre composites while also reducing the negative effects of production processes on the environment. The development of these composites has been greatly aided by areca nut sheath fibre epoxy composites, which have applications in construction materials, biodegradable packaging, and other areas. In this research, areca nut sheath reinforced epoxy composites were tested for their mechanical and thermal characteristics along with their durability (weathering). It was observed that areca nut sheath fibre reinforcement improved both the tensile, flexural and impact properties of the composites due to their effective reinforcement, fibre–matrix interaction and load bearing capability. However, this study demonstrates that composites containing 20% areca nut sheath fibres have the best tensile and flexural strengths. Weathering studies revealed that the durability slightly decreased upon exposure to moisture and vermicompost due to moisture intake by the fibres.
