Abstract

This
study explores the effects of nanoclay addition on mechanical response of
Glass/Carbon/Glass fiber (G/C/G) reinforced epoxy matrix composite laminates
under tensile and flexural loadings. Organomodified nanoclay containing
Glass/Carbon/Glass hybrid composite laminate was evaluated for dynamic
mechanical properties as well as mechanical strength, stiffness and ductility.
Two different types of fiber reinforced hybrid composites were manufactured.
The amount of nanoclay additions were 0.75 wt % and 1.25 wt % with respect to
epoxy resin and hardener. A nanoclay containing epoxy – Glass/Carbon/Glass
hybrid composite laminate were manufactured by using a hydraulic hot press.
Then, tensile, flexural tests and dynamic mechanic analysis (DMA) was
implemented to ASTM standard specimens which were cut from the plates by using
abrasive water jet cutter. Uniaxial tensile and three-point bending tests have
been carried out to obtain some mechanical characteristics such Young’s
modulus, tensile strength, break strain, flexural strength and modulus of the
hybrid composites. DMA measurements also performed to compare nanoclay effect.
The results of this study demonstrated that the mechanical behavior was
positively affected by nanoclay addition into epoxy resin. The tensile strength
and flexural strength significantly increased compared to the non-nanoclay
hybrid composite (pure). However glass transition temperature (Tg)
of hybrid composites decreased with increasing amount of nanoclay.
