With the growing use of composite materials in different fields, including aerospace, marine, architecture, automotive, sports and recreation, the need to join dissimilar composite materials has arisen. In this study, the work is aimed at fabrication and testing of Fiber reinforced plastic (FRP) hybrid lap joints. We emphasize on analysing joint strength, efficiency of different Fiber reinforced materials (Carbon fiber, Glass fiber, Carbon+Glass fiber). We find the joint strength of GFRP-128.03Mpa, CFRP+ GFRP-478.42Mpa, CFRP-578.47Mpa. A finite element analysis has been carried out using ANSYS in order to obtain stress distribution of the hybrid composite lap joint. With the results of the finite element study and experimental Comparison, joint strength of different composite materials are compared, and design suggestions were made based on these results.

Abstract


With the growing use of composite materials in different fields, including aerospace, marine, architecture, automotive, sports and recreation, the need to join dissimilar composite materials has arisen. In this study, the work is aimed at fabrication and testing of Fiber reinforced plastic (FRP) hybrid lap joints. We emphasize on analysing joint strength, efficiency of different Fiber reinforced materials (Carbon fiber, Glass fiber, Carbon+Glass fiber). We find the joint strength of GFRP-128.03Mpa, CFRP+ GFRP-478.42Mpa, CFRP-578.47Mpa. A finite element analysis has been carried out using ANSYS in order to obtain stress distribution of the hybrid composite lap joint. With the results of the finite element study and experimental Comparison, joint strength of different composite materials are compared, and design suggestions were made based on these results.
