The Change of Mechanical Properties of Acorn Powder Reinforced Polystrene and Polyoxymethylene due to Gamma Radiation
Abstract
In the
present study, the effects of gamma radiation on the mechanical properties of
acorn powder reinforced polystyrene (PS) and polyoxymethylene (POM) were
investigated. Different amounts of acorn powder reinforced PS and POM samples
were produced by using a plastic injection machine and these samples were
exposed to 45 kGry gamma irradiation. Subsequently, the test samples were
examined for the changes in their tensile, three-point bending and Izod impact
strengths and the effect of gamma irradiation on the samples was established
through comparing the findings with the pre-radiation state. With the
increasing amount of acorn powder, the tensile strength of acorn powder
reinforced PS and POM materials decreased. In contrast to the tensile strength,
the bending strength of the samples increased with the increasing amount of
filler material. In addition, an increase in
the mechanical properties such as tensile and bending strength of
materials exposed to gamma radiation has occurred.
