Effect of Silicon Carbide Addition and Jute Fiber Surface Treatment on Functional Qualities of Low-Density Polyethylene Composites

In the modern era, advanced hybrid polymer-based composites have the potential to replace conventional polymers and exhibit unique behaviour. This study focuses on low-density polyethylene (LDPE) hybrid composite made with jute fiber and enhanced with nano silicon carbide particles through the injection moulding process. The natural jute fiber undergoes chemical surface treatment to improve its adhesive behaviour. The study evaluates the effects of 10wt% chemically treated jute fiber and 1, 3, and 5wt% of SiC on the structural, impact, tensile, and flexural strength of the synthesized composites according to ASTM D7565, D3039, and D790 standards. The structural behaviour of LDPE composites is assessed through X-ray diffraction analysis, revealing improved crystalline structure and interaction. Among the five prepared composite samples, the composite containing 10wt% treated jute fiber and 5wt% SiC demonstrated enhanced impact, tensile, and flexural strength of 5.7 J/mm², 43 MPa, and 56 MPa, respectively.
