| Summary: | The aim of this study was to evaluate the effects of irradiation on structural, mechanical and thermal properties of PAN- carbon fiber composite. The overall applied doses were 250, 500, 750, and 1000 kGy. Irradiated and non-irradiated samples were characterized by Scanning electron microscopy, Fourier transform infrared spectroscopy and differential scanning calorimetry. Tensile strength test was conducted in order to measure mechanical properties. Scanning electron microscopy was used to evaluate microstructural behavior. Thermal behavior of the samples was studied by thermogravimetric analysis and differential scanning calorimetry. The results showed that by increase in Gamma and Electron doses the thermal behavior of the composite indicated higher decomposition degree as a function of temperature. Electron irradiated relatively smoothed surface of carbon fibers than that of virgin fibers and after γ treatment the bulges were decreased and surface was unrough. |
