Abstract

Polybenzoxazines are novel phenolic polymers that have found application as the precursor matrix in carbon-carbon composites due to their high char yield. A furan-based difunctional benzoxazine was selected for this study due to its high theoretical char yield of 74 %. The furan-based difunctional benzoxazine was synthesized using bisphenol A, furfurylamine and paraformaldehyde. Temperature ramp rate during carbonization was investigated to determine its influence on char yield and carbon microstructure. A maximum char yield of 54.8 % was observed for pyrolysis ramp rate of 1 °C min-1. The char yield decreased 6 % between ramp rates of 1 and 20 °C min-1. The carbon microstructure was investigated using scanning electron microscopy (SEM). As pyrolysis ramp rate increases, an increase in the microporosity can be seen. The results show that slower ramp rates increase char yield and decrease microporosity for a furan-based difunctional benzoxazine.
