Composite materials undoubtedly hold a significant place among engineering materials. Their applications are
increasing due to their many properties, such as strength, lightness, high fatigue strength, and creep resistance. In
addition to these superior properties, numerous studies are being conducted to improve the mechanical properties
of polymer matrix composites. Factors such as fiber structure, variation in fiber angles, and the manufacturing
method of the composite material affect the mechanical properties of composite materials. In addition to these
methods, the additives added to the matrix also have an impact on mechanical properties. These additives can be
natural clays or nano-sized particles. In this study, the mechanical properties of epoxy resin composites with
perlite were experimentally investigated. Tensile values of composites containing 0.1%, 0.3%, and 0.5% perlite
by weight were compared with those of composites containing no additives (i.e., 0% epoxy resin composites).
The samples were subjected to quasi-static compression tests at room temperature. Removing the 0.5% perlite
addition resulted in the lowest tensile value of 27.12 MPa. The highest tensile value was obtained with the epoxy
resin composite containing 0% perlite, i.e., no perlite addition. Increasing the perlite content had negative effects
on mechanical properties. It was observed that the addition of perlite had an effect on the elasticity of the samples.
Among the perlite-added samples, the highest result of 27.87 MPa was observed in the sample with the lowest
perlite addition, i.e., 0.1%.
