نبذة مختصرة : Epoxy resins are a very common type of adhesive materials in several fields like the automotive industry, marine, probably the most important is in the aerospace industry. Adhesive joints of carbon fiber reinforced epoxy composite laminates are worked using an epoxy resin as the adhesive. In this paper, Adhesive joints were modified nano-CaCO3 in order to enhance the shear strength of epoxy adhesives. The enhancements of shear strength of epoxy adhesive joints reinforced with different nano-CaCO3 particles loading have been studied. The adhesive properties were measured by tensile lap shear test as a function of nano-CaCO3 amount and damaged adhesive surface roughness. Also, the fracture surfaces were examined with Scanning Electron Microscopy (SEM)
