Fabrication and characterizations of screw pine root fiber reinforced soy composite as sustainable green composite

Abstract

AbstractScrew pine root fibers are engineering fibers that have yet to be explored in terms of its chemistry with bio‐resin in biodegradable composites to replace nonbiodegradable thermoplastics used in packaging, automobiles, furniture, and industrial sectors. Screw pine root fibers are reinforced with soy, poly(vinyl alcohol), and soy‐poly(vinyl alcohol) resin systems in this work to create a variety of composites. Composites demonstrated highest amount of tensile strength at around 39.7 MPa, 37.6 MPa of flexural property, along with an impact strength around 12.4 kJ/m2. The thermal solidity of the optimized material was determined to be 235°C. After 24 hours of immersion, the composite had the lowest water absorption of 18.4%. All composites were shown to be biodegradable, losing about 54.2%–72.9% of their original mass after 60 days in soil burial. Unique characteristics such as the use of low‐cost agricultural materials, water‐based resin, stable composite, and properties such as moderately strong, safe disposal after service periods make these manufactured composites market feasible as consumer‐friendly/ecofriendly green products.Highlights Screw pine root fibers were extracted from waste roots and used as reinforcement. The tensile strength of the composite was achieved as 39.7 MPa. The water absorption of hybrid composite was found 30.8% after 24 h. After 60 days under soil burial, composite lost 67.5% of its original weight Developed composites can be good alternant for nondegradable thermoplastic.
