Mechanical loadings are applied to polymer materials, which are used in mechanical engineering applications. Usually, photopolymer fails to meet them, so some modification must be done to the polymer material. Adding fillers and fibers to the polymer will strengthen it by the polymer blending method. In this investigation, mechanical properties of glass fibers and carbon fibers and combinations of glass and carbon fiber are added to polymer composites. Considerable effort has been made to find the effect of impact loading on hybrid composites. Based on earlier investigation The 80% PA66 and 20% PP blend composition have average mechanical properties. As a result, the base material of this research work for future development of polymer hybrid composites has an 80/20 wt% blend composition. Effects of short glass fiber, short carbon fiber, and combinations of these two on physical and mechanical properties are assessed. It has been found that the combination of carbon and glass fiber in blend form of 80 and 20 wt exhibited excellent physical and mechanical properties in comparison with glass and carbon fiber added to it. Hybrid composites achieved a balanced improvement, combining the advantages of both fibers, with tensile strength increased by approximately 50% and a moderate Young’s modulus enhancement. These findings highlight the hybrid composite’s potential as a lightweight material with optimized mechanical properties for applications requiring high tensile performance and flexibility.
