Comparable Analysis on the Thermal Performance of Prepreg

Abstract:

Both differential scanning calorimetry (DSC) and differential thermal analysis (DTA) were employed to analyze the thermal performance of the prepreg made by different companies. The results were shown that glass transition temperature (Tg), conversion rate and residual amount of carbon had a large difference. Tg ranged from 130.10 °C to 198.99 °C. After heat-treating from 20°C to 230°C for 23minutes, conversion rate ranged from 19.47% to 100%. After heating from 20°C to 500°C, residual amount of carbon had a range from 13.149% to 39.834%. Tg was not directly proportional to residual amount of carbon. When the residual amount of carbon was more than 30%, Tg would be more than 150°C. It was indicated Tg was relevant to carbon content of resin and inorganic fillers.
