The use of ceramic fiber reinforcements was investigated in comparison to traditionally utilized carbon fiber ones in relating to thermal resistance for bismaleimide composites. BMI resins were reinforced with carbon fibers, with ceramic fibers or particles, such as SiC and Al2O3. From dynamic and isothermal thermogravimetric experiments in air, the activation energies of degradation of composites were determined and compared. It was observed that the fiber/polymer interaction was an important parameter in degradation phenomena. Also, it was observed that the thermal resistance of ceramic fiber BMI composites was improved after ageing in air, while carbon fiber BMI composites exhibited the opposite trend.
