Abstract

This study aimed to
investigate the effect of graphene nanoplatelets (GnPs) on the tensile and
flexural properties of fiber reinforced composite material. For this purpose;
an experimental study was conducted using composite materials which were
manufactured with [(0/90)₆]_s glass fiber and epoxy matrix
by vacuum assisted resin transfer method. Glass fiber reinforced (GFR) epoxy
composite plates were manufactured with various graphene nanoplatelets content
such 0, 0.1, 0.25 and 0.5 wt% inclusion. Maximum tensile and flexural strength
values were obtained in 0.1 wt% GnPs filled composites. After this weight
content, decreasing trend in the strength values was observed. When fractured
specimens were examined, failure modes were supported the test results also.
Higher contents of GnPs were resulted as agglomeration in matrix mixture lead
to impurities and stress concentrations, thus lower strength values were
obtained in composite.
