“…Benzoxazine is a newly developed thermosetting resin, which can be synthesized by Mannich condensation from phenol, amine, and formaldehyde (Holly and Cope, 1944;Ning and Ishida, 1994). The major advantages of polybenzoxazine include excellent mechanical and thermal properties, low water absorption, high char yield, and low surface free energy (Ishida and Allen, 1996;Ishida and Low, 1997;Kim et al, 1999a,b;Wang et al, 2006;Velez-Herrera and Ishida, 2009;Yagci et al, 2009;Zhang et al, 2012Zhang et al, , 2013.…”
