| 摘 要： | 通过热重法研究了玄武岩纤维/S-157酚醛树脂复合材料(BF/S-157)在惰性气氛下的热稳定性,计算了该材料的热分解动力学参数,推断出其热分解反应机制及非等温动力学机理函数。Ozawa法、Kissinger法计算得到BF/S157热分解平均活化能分别为228.4kJ.mol-1和230.0kJ.mol-1;Coats-Redfern法分析表明,BF/S157热分解反应初期的反应机制为扩散反应,末期时为化学反应,期间为过渡阶段。

| Abstract: | The thermal stability of basalt fiber reinforced phenolic resin S-157 composite(BF/S-157)in N2 was studied by TG-DTG technique.The non-isothermal kinetics data were ana1yzed by Ozawa method and Kissinger method,respectively.The most probable kinetic mechanism function was suggested by Coats-Redfern method.During the initial reaction stage,the thermal decomposition mechanism was diffusion reaction.During the final reaction stage,the thermal decomposition mechanism was chemical reaction. |
