Abstract

The aerospace and automotive industries have experienced a substantial surge in interest in innovative composite systems driven by the ongoing demand for lightweight, high-performance materials. In this study, the mechanical properties of zinc (Zn) matrix composites reinforced with fluorapatite particles (Fap) are examined as a function of thermal treatment. Within the context of this investigation, we endeavoured to create composite materials containing Zinc-Fluorapatite powder. Stir casting was used to produce both Pure zinc composites and Fap composites. A variety of compositions were taken, and all samples underwent mechanical characterization, namely, a tensile test. The samples were heat-treated in the furnace after casting to assess their behaviour. The findings suggest that mechanical properties are highly dependent on the heat treatment used. The ultimate tensile strength of the samples treated at a specific temperature for a specific duration was found to be significantly increased. This was because particle dispersion improved, and interfacial bonding between the Zn matrix and the Fap reinforcement increased. The yield strength of the 1% Fap composites was found to be 40 MPa, while their ultimate tensile strength was found to be 60 MPa. The yield strength of the pure zinc sample is 55MPa, while the ultimate tensile strength of the sample is 70MPa.
