Composite materials are increasingly securing their place in industry. These materials, which have superior
properties compared to metals in many areas, increase their usability. Despite the many superior properties of
composite materials, research aimed at improving their mechanical properties is also gaining momentum. These
include the addition of nanoscale additives. These nanoscale materials can sometimes be natural clays, while other
materials such as graphene and carbon nanotubes (CNTs) are also used. In this study, the mechanical properties
of carbon nanotubes added to epoxy resin composites were experimentally investigated. Epoxy resin matrix
composite samples containing 0.5%, 1%, 3%, and 5% carbon nanotubes were compared with 0%, or unadded,
composites. Vacuum infusion was applied during the production of the samples to ensure a homogeneous mixture.
Quasi-static compression tests were conducted to determine the mechanical properties of the samples. It was
determined that the addition of carbon nanotubes to epoxy resin composites reduced the maximum stress value.
The maximum stress value obtained with 0% epoxy resin was found to be 30 MPa. The greatest decrease in
carbon nanotube additions was observed with a 5% carbon nanotube addition, which reduced the tensile strength
by 29.93%. The least decrease was observed with a sample containing 1% carbon nanotube, a 7.63% decrease.
After the 1% carbon nanotube addition, the tensile values of the composite samples decreased again. The tensile
values of the epoxy resin composites were observed to be very close to each other when carbon nanotubes were
added at 0.5% and 3%.
