  Abstract

BA-a polybenzoxazine composite reinforced with cellulose nanocrystals was successfully prepared to improve the brittleness of polybenzoxazine resin. The thermally induced crosslinking behavior was investigated using differential scanning calorimetry (DSC), and the thermal stability of the composites was evaluated using thermogravimetric analysis (TGA). The brittleness of the composites was also evaluated using measures of flexural strength and strain. We demonstrate that the flexibility and thermal stability of the composites can be improved using cellulose nanocrystals (CNCs) as reinforcements.
