Abstract Kevlar-reinforced epoxy composites are widely employed in high-performance applications due to their excellent strength-to-weight ratio and impact resistance. However, limitations wear resistance hinder use under abrasive conditions. To address this, Alumina (Al2O3) was incorporated as particulate filler at 2%, 4%, 6% by weight. Composite laminates were fabricated using hand layup followed compression molding, with a constant Kevlar fiber content of 30 wt%. Mechanical testing conducted per ASTM D3039 (tensile), D790 (flexural), D785 (hardness) standards, while behavior evaluated dry sliding conditions G99 pin-on-disc setup 10 N load, 1.5 m/s velocity, 500 m distance. The addition 4% alumina yielded optimal performance, resulting 28% increase tensile strength (from 98 MPa 126 MPa), 21.6% flexural 152 185 12.2% hardness 82 HRB 92 HRB) compared the control. rate reduced from 3.12 × 10−4 mm3/N·m control 1.89 alumina, representing 39.4% improvement. coefficient friction also decreased 0.52 (control) 0.46 alumina.

Currently, research on composite materials derived from natural fibers and agro-industrial waste has generated industrial proposals for producing useful with sufficient mechanical strength applications involving the reuse of secondary purposes. The objective this study was to determine influence fiber content final tensile material, serving as a reference manufacture plates. To achieve this, high-density polyethylene (HDPE) composites reinforced short banana were prepared using blade mill hot compression molding techniques. Two levels content—10% 20% by weight—were used, along two types HDPE: virgin recycled. We evaluated effect adding properties composite, specifically strength, according ASTM D638 standard polymeric materials. These results correlated structural obtained through morphological, chemical, thermal characterization developed evaluation showed that elastic modulus depend type polyethylene. Thermogravimetric analysis revealed decompose faster than pure polymers (virgin recycled HDPE). Based these findings, material under optimal conditions is recommended use in walls or construction boards where high not critical, due decreased resulting incorporation waste.
