Abstract

Benzoxazine resins suffer from high curing temperature and low crosslinking density, which restrict wide application. In this work, melamine (MA) and phenylsubstituted melamine (BG) were simultaneously used as amine sources to prepare high-performance, processable benzoxazine resins with adjustable curing reactivity. The curing behavior of benzoxazines was evaluated by rheology and DSC. Notably, glass fiber laminated composites with melamine benzoxazine as resin matrix showed ultra-low CTE and excellent thermal expansion properties, especially toughness. In particular, the Z-axis CTE of composites with BG added can be as low as 0.8 ppm/℃ over a wide temperature range, providing ideas for developing high-performance benzoxazine resins with good processability.
