Kompozit malzemeler üzerindeki çevresel etkilerin incelenmesi

In this research, an investigation of the environmental effects on composite materials has been conducted. The composite material with a polymeric basis was prepared by hand casting and is consisted of epoxy as a base material reinforced by glass fibers and with three layers and in a random direction. The research was carried out on three stages. The first stage is preparing the samples from the composite material that consists of epoxy reinforced with glass fiber. As for the second stage, the prepared samples were exposed to certain environmental conditions where the sample 2 was exposed to moisture for a one month by immersing it in water, and exposing the sample 3 to a temperature of 50 °C for a one month, exposing the sample 4 to a temperature of 70 °C for a one month, while not subjecting the sample 1 to environmental conditions. The third stage is to procedure a hardness, tensile, bending and impact resistance tests on the prepared samples. It was observed from the results that mechanical properties decrease when exposed to environmental conditions such as moisture and heat, and it was also observed that the effect of moisture is less than the effect of heat on mechanical properties, as well as the temperature effect on the mechanical properties which increases when temperature increases.
