Abstract

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).

Keywords
