Studying The Effect of Gamma Rays on The Impact Strength and Wear Properties of Silicon Carbide SIC and Graphite Gr Nanocomposites
In this paper, composite materials were prepared using epoxy as a base material supported by nano - silicon carbide and nano - graphite particles with different weight fractions (2%, 4%, 6%) for each separately by manual molding method. Some mechanical properties (shock strength, wear resistance) of...

| Summary: | In this paper, composite materials were prepared using epoxy as a base material supported by nano - silicon carbide and nano - graphite particles with different weight fractions (2%, 4%, 6%) for each separately by manual molding method. Some mechanical properties (shock strength, wear resistance) of the samples were studied under natural conditions and after exposure to gamma rays at different doses (6,8,10 KGy) and for different periods of time. In normal conditions, it was found that the values of impact resistance increased for for all samples the composites reinforced with (SiC) and decreased for the composites reinforced with (Gr) and it increase for all samples when exposed to gamma rays . It was found that the wear values decrease with increasing reinforcement percentages for all samples and Values decrease for all superimposed samples when exposed to gamma rays and continue to decrease with increasing irradiation period and be less than it is in circumstances. The materials prepared in this study can be used in sliding and rotating places because their wear coefficient is very low. They can also be used to attenuate low doses of gamma rays. They can also be used as containers for transporting goods because their shock strength is high. |
