Abstract
The mechanical and vibrational isolation properties of reinforced carbon fibre composites, such as carbon fibre [0]7s/epoxy, carbon fibre [0]6s/Graphene nanopowder/epoxy, and carbon fibre [0]4s/epoxy/Al 6061, are investigated in this research. Ultrasonic stirring was employed in a carbon fiber/graphene-nano powder laminate to reinforce 0.5 weight percent graphene nanoparticles with the resin. The effect of nano-fillers and metal laminate in the carbon fiber composite specimen was analysed by considering glass transition temperature, flexural modulus, and natural frequency. The results show that the Carbon Fiber Reinforced Polymer (CFRP) with graphene shows a 16.9% and 57.5% increment in flexural strength compared to CFRP and CFRP with Al6061 alloy. In contrast, in the DMA test, the glass transition temperature and other parameters show the least difference, whereas the loss modulus is 34.3% and 67% high for CFRP compared to CFRP/graphene and CFRP/Al6061 samples. Furthermore, using graphene nanopowder and aluminium plates reduces the carbon epoxy laminate’s inherent frequency.
