Abstract

Hybrid composites are becoming useful because they have better qualities than regular composites. This study examines the conventional properties of composites that utilise SiC and Al2O3 as filler components. Kevlar, S-glass, and sisal fibers at 90° and 0°, followed by additional layers of S-glass and Kevlar. To make sure that the material qualities were the same throughout, the resin and fibre layers were arranged in an alternating pattern. Mechanical testing showed that important performance parameters have improved a lot. The tensile strengths of laminates using SiC and Al2O3 were 93.4 MPa and 92.8 MPa, respectively. The flexural strength values were 37.5 kJ/m² for SiC and 32.9 kJ/m² for Al2O3. Hardness tests showed considerable improvements, with SiC-reinforced composites getting 65.33 HV and Al2O3 – reinforced composites getting 57 HV. The interlaminar shear strength for SiC was a little greater, at 212.0 MPa, than for Al2O3, which was 211.6 MPa. These results show that SiC and Al2O3 fillers could be useful in hybrid composites because they provide a good mix of strength, thermal stability, and wear resistance. The findings suggest that these materials are suitable for customization in demanding engineering applications, enhancing mechanical reliability and durability. Future research will focus on improving filler formulations and examining their effects on qualities like fatigue resistance and impact strength.
