Polybenzoxazines, also known as Benzoxazine (Bz) is one kind of high‐performance thermoset polymers. It manifests several advantages when used for thermal protection applications, such as thermal and dimensional stabilities, low rate of moisture absorption and near zero volatility in curing process....
