What is it about?

The aim of this research is to measure the thermal conductivity for epoxy resin as a base material, Nano ceramic powder (SiC) with particle size (64.85nm), and nano Graphite powder with particle size (87.85 nm) are used as a reinforcement materials in composites preparating in different weight fractures (2%, 4%, 6%),while the Hybrid (SiC-Graphit) model are prepared by another weight fractures of (SiC and Graphite), Hand-casting method was used in preparation the research samples.

Why is it important?

The results show an increase in the thermal conductivity values after the irradiation compared with the results of thermal conductivity in normal conditions. It is worth noting that an atomic force microscope (AFM) has been used to measure the particle size of nanomaterials.


The thermal conductivity of the (EP+SiC),(EP+Gr)and Hyb (Gr+SiC)composites increased when radiation doses increase . The thermal conductivity of the composite (EP+SiC)and (EP+Gr)and Hyb(SiC+Gr)increases by increasing the reinforcement ratios, results from others at weight fracture (2%,4%,6%). The (EP+Gr) composite gives best results in weight fractures(2%,4%,6%).From the other.
