Abstract:

In this study, the effect of functionalized nanoclay (with silane and amine groups) on the mechanical properties and impact behavior of glass fiber / Kevlar-epoxy hybrid composites was experimentally investigated. Nanoclay functionalized at three different concentrations (0%, 1%, and 3%) was mixed into the epoxy resin. Composite samples with layer 12 have been manufactured by handlay-up method. The mechanical properties and impact behaviors under 30J were examined on the prepared composites. The comparisons between the nanoclay and non-nanoclay samples were carried out by using contact force, deflection, impact energy, velocity and time data of the impact tests. Mechanical strength and impact properties of 1% nanoclay added hybrid composites how better performance than that of 0% and 3% nanoclay added hybrid composites. As a result of the good dispersion of clay in the matrix-fiber interface in samples with 1% nanoclay addition, the impact values are reduced by 10% and load bearing capacity is increased to 22%. Futhermore, among bare and 3% nanoclay added hybrid composites, the highest hardness value of 23.60 HV obtained from 1% nanoclay added hybrid composite structures.
