| Abstract: | Curing process of benzoxazine and benzoxazine/CF composites was measured by non-isothermal differential scanning calimetry at different scanning rates. The characteristic temperature, reactive heat, reactive rate of BA-a and BA-a/CF at different scanning rates was analyzed. The apparent activation energies and reaction order of both cure systems were obtained by Kissinger equation. The results show that the cure reaction of benzoxazine can be catalyzed by carbon fibers. At the same time, carbon fibers slow down the cure reaction of benzoxazine. The reason of it was simply analyzed. |
