^{The mechanical properties of different polymer matrix composites are discussed in this research study. These composites are}^{multiphase materials in which reinforcing elements and a polymer matrix are suitably combined. The mechanical properties of}^{18 PMCs, including nylon 66 reinforced with 5, 15, and 25% wt% silicon carbide (SiC) and nylon 66 reinforced with 5, 15, and}^{25% wt% boron carbide (B4C), were evaluated using an injection moulding technique at three different injection pressures in}^{this study. The optimization of process parameters like reinforcement material, reinforcement quantity, and injection pressure}^{to maximize the tensile and impact strength of nylon 66 composites are the main focus of this study. It is observed that the}^{specimens 25% SiC with an injection pressure of 90 MPa has optimised tensile strength, while the specimen 5% B4C with an}^{injection pressure of 90 MPa has optimised impact strength.}
