Abstract
Hybrid aluminum matrix composites (HAMCs) are the second era of composites that can possibly substitute single strengthened composites because of improved properties. The present investigation used stir casting techniques to fabricate the hybrid metal matrix composites with different volume fractions Al-χ%TiO2- χ % SiC (χ −2.5%, 5%, 7.5%). This paper examines the feasibility and relevance of the growing minimum effort of hybrid composites (AA6061-TiO2-SiC) for brake pad applications in automobile industries. An optical electron microscope (OEM) was used in HAMCs, which indicates that the reinforcement is very scattered in the Al matrix alloy and the porosity level is adopted for the stirring composites. The mechanical properties such as Tensile strength (TS), Hardness (BHN), density and impact strength of the hybrid composites have been seen as either practically identical or better than the earthenware strengthened composites. This is seen from past research that identifies the direct reinforcement of the composites due to the proximity of the hardened porcelain phases, while the indirect reinforcement arises from the thermal mismatch between the matrix and reinforcement during the solidification process. It has been reasoned that the hybrid composites offer greater flexibility and dependability in the structure of potential parts relying on the fortification's mix and organization.
