Aluminum is used widely in automobile because of its light weight and fuel economy compared to steel. Joining is one of the most crucial part in manufacturing decision of aluminum and therefore significant in design. The aim of this research is to produce nanofiller from graphite materials for toughening adhesive and determining its mechanical properties. In other word, creating a physical joining which consists the mixture of epoxy and modified nanographite for aluminum panel. The weight percentage of the modified nanographite used is 1%, 1.75% and 2.5%. Two type of analysis were made which are mechanical properties and morphological structure. The analysis of mechanical properties consists of tensile test, porosity density and double cantileber beam test. Result from tensile test showed that 1wt% of modified nanographite produces the highest maximum strength of 2.305 MPa. For porosity density test, it shows that 1 wt% of modified nanographite indicated the lowest value of 1.10%, in which affects the mechanical properties of composite significantly. For double cantilever beam test, the results of 1wt% modified nanographite obtained were 6265.32 J/m2 and 9397.98 J/m2 for the respective crack lengths 37.5 mm and 25mm. The method used for pre-crack was a non-sticky thin film in adhesives. From both results, it showed that 2.5 wt% modified nanographite produces the lowest value of adhesive strength which mean that adding too much modified nanographite will reduce the brittleness of epoxy thus the strength of adhesive will reduce. For the morphological structure, Scanning Electron Microscopic (SEM) was used in order to observe the dispersion of nanographite inside the composite. Overall, the research reveals that the adhesive towards aluminum metal is successfull. However, an in-depth study still need to be carried out in order to improve the composite's mechanical properties.
