Abstract

Epoxy resin is a class of thermosetting polymers that are widely used due to their excellent mechanical strength, good adhesion properties, chemical resistance, and electrical insulation characteristics. The fracture behavior of pure epoxy resin is studied under varying loading rates. In this paper, we study by toughening the epoxy resin with multi-walled carbon nanotubes (MWCNTs) and alumina nanoparticles (ANPs).The investigation tested specimens, including Unnotched and SENT specimens, under tensile loading conditions. The fracture behavior of pure epoxy resin is studied under displacement loading rates of 0.01, 0.05, 0.5, 5, 50, and 500 mm/min. The size effect testing methodology is adopted to prepare geometrically similar specimens with geometrically similar notches. With the increase in loading rate, the mechanism of failure transitioned from brittle mode to quasi-brittle mode characterized. The fracture parameters increased monotonically as the quantity of MWCNTs and ANPs increased at the optimum weight fraction.
