Because of the inherent brittleness property of monolithic epoxy, it fails to prevent crack propagation and is hence vulnerable to the catastrophic failure. Nano-fillers, such as CNT/Graphene (GnP)/Nanodiamond (NDs) and other carbonaceous materials increase its ability to withstand crack propagation thus its fracture strength propitiously improved. This paper studies compressive properties of MWCNT/GnP/NDs on epoxy based composite material. A static uniaxial compression test was conducted in order to study the effect of these fillers on the compressive stress-strain behaviour of such composites. In this study, the MWCNT/GnP/NDs are added individually as 0.2 wt% and for the hybrid composite, 0.1 wt. % of NDs is added separately along with 0.1 wt% of MWCNT and GnP to the epoxy matrix. The bonding between MWCNT/GnP/NDs with the epoxy matrix is confirmed by microscopic observations. The results showed that the individual addition of 0.2 wt% of MWCNT/GnP/NDs, improves the compressive strength whereas the hybrid composite produced a declining trend. The reverse trend was also observed for the modulus value of the above mentioned composite materials.

Abstract


Because of the inherent brittleness property of monolithic epoxy, it fails to prevent crack propagation and is hence vulnerable to the catastrophic failure. Nano-fillers, such as CNT/Graphene (GnP)/Nanodiamond (NDs) and other carbonaceous materials increase its ability to withstand crack propagation thus its fracture strength propitiously improved. This paper studies compressive properties of MWCNT/GnP/NDs on epoxy based composite material. A static uniaxial compression test was conducted in order to study the effect of these fillers on the compressive stress-strain behaviour of such composites. In this study, the MWCNT/GnP/NDs are added individually as 0.2 wt% and for the hybrid composite, 0.1 wt. % of NDs is added separately along with 0.1 wt% of MWCNT and GnP to the epoxy matrix. The bonding between MWCNT/GnP/NDs with the epoxy matrix is confirmed by microscopic observations. The results showed that the individual addition of 0.2 wt% of MWCNT/GnP/NDs, improves the compressive strength whereas the hybrid composite produced a declining trend. The reverse trend was also observed for the modulus value of the above mentioned composite materials.
