Abstract

This study examines the mechanical properties of hybrid composite laminates reinforced with Kevlar, sisal, and S-glass fibers, and incorporating ceramic fillers—silicon carbide (SiC) and aluminum oxide (Al2O3)—within an epoxy matrix. The hand lay-up method was utilized to produce the laminates, ensuring a uniform fiber stacking sequence and including 10% filler material. Two composite variations were synthesized: one incorporating SiC and the other Al₂O₃, and both underwent tensile, flexural, hardness, and inter- laminar shear strength (ILSS) assessments. The SiC-filled laminate exhibited greater tensile strength (93.4 MPa) than the Al2O3-filled variant (92.8 MPa). The flexural strength results preferred the SiC composite (37.5 kJ/m² compared to 32.9 kJ/m²), and hardness values exhibited a significant increase with SiC (65.33 HV) over Al2O3 (57 HV). The inter-laminar shear strength of the SiC laminate (212.0 MPa) was somewhat superior to that of the Al2O3 variant (211.6 MPa), suggesting enhanced bonding and delamination resistance. Analytical modeling via stiffness matrix computation and finite element simulation with ANSYS validated the experimental trends, corroborating the mechanical superiority of the SiC composite. The results confirm that the Kevlar/Sisal/S-glass hybrid composite with SiC filler provides the optimal combination of strength, durability, and stiffness. The optimum composite, characterized by its balanced mechanical properties, low weight, and resistance to mechanical stresses, is ideally suited for automotive structural components, especially car bumpers, where impact resistance and structural integrity are paramount. Nonetheless, owing to apprehensions over water absorption, these composites are not advisable for underwater applications.

Keywords: Cryogenic Treatment, Mild Steel, Mechanical Properties, Tribological Behavior, Wear Resistance, Machinability.
