Investigation on mechanical and acoustic properties of natural fiber-based sustainable green resin hybrid composites

Abstract

The use of natural fibers has been suggested by researchers for the purpose of promoting environmental sustainability. In this work, hybrid composites made of coir and banana fibers were fabricated by using both green resin and epoxy resin in the preparation of composites. Soybean oil is used in this work as the eco-friendly resin. To determine the mechanical characteristics of the composites, a number of experiments were carried out including tensile, compression, hardness and impact tests. In addition, testing was done on the sound absorption qualities. Composites composed of green resins exhibit superior environmentally friendly characteristics and mechanical robustness in comparison to composites based on epoxy resin. The tensile strength of the hybrid composites exhibited superior performance compared to other hybrid composites. The additional mechanical qualities of the hybrid composites are noteworthy and serve as a driving force to pursue the development of specific applications. Highlights: Hybrid composites exhibit superior mechanical properties. The use of natural resin-based composites is limited. There is a potential scope for developing hybrid composites using natural fibers and resin for acoustic applications.
