Abstract

In this research, the optimization of composite materials for improving their mechanical properties is investigated. It is achieved by applying different compositions of the PTLLDPE matrix, SiC nanoparticles, and carbon fibre filler. For this purpose, six composite samples are prepared using different compositions of PTLLDPE from 40% to 60%, SiC nanoparticles from 0% to 3%, and carbon fibre filler from 10% to 20%, which are mechanically tested . Results show that tensile strength increases with increasing PTLLDPE contents, Sample 6 having the highest value of 62 MPa. As the SiC nanoparticles contents increase, the flexural strength and impact resistance increases, Sample 4 having the highest flexural strength at 75 MPa and impact resistance at 200 J/m². The hardness increases with increasing carbon fiber fillers, Sample 6 having the highest hardness value at 88 shore D. This is important in the synthesis and the optimization of composite formulations, helping various industries in in their choice and application of the composites.
