Flexural Behavior of Graphene Nanoplatelets Reinforced Cross-Ply E-glass/epoxy Laminated Composite Materials
Abstract
In this study, the
effect of graphene nanoplatelets reinforcement on the flexural strength of E-glass/epoxy laminated composite material
was investigated experimentally. [0⁰/90⁰]3S oriented composite
materials with and without graphene nanoplatelets reinforcement were
manufactured by using hand lay-up and vacuum bagging method. Graphene nanoplatelets at three different ratios
(0.25, 0.5 and 1 wt.%) were added to the epoxy. The produced plates were cut
with a water jet cutting machine to obtain three-point
bending specimens. Then, three-point bending tests were performed according to the
ASTM D790 standard. The span between the centers of support cylinders/composite
specimen thickness ratio (s/t) was selected as 16 in all the tests. Results
indicate that the addition of graphene nanoplatelets to the epoxy matrix
increased the flexural strength of the laminated composite material. When the graphene nanoplatelets at ratios of 0.25,
0.5 and 1 wt.% were added to the epoxy
matrix, the flexural strengths increased by 4.32%, 12.88% and 7.03% respectively.
