中文摘要：

采用非等温DSC方法研究了不同升温速率下热致性液晶聚合物（TLCP）/酚醛树脂（PF）复合体系的固化行为,利用3种现象学模型（Ozawa及Kissinger简单模型、Kissinger-Akahira-Sunose（KAS）等转化模型）分析对比了TLCP/PF复合体系及纯PF体系的固化反应动力学,研究TLCP含量对TLCP/PF复合体系固化反应动力学的影响。结果表明,采用Ozawa和Kissinger2种方法计算得到TLCP/PF复合体系的固化反应活化能（Ea）结果一致;通过KAS模型得到TLCP/PF复合体系不同的固化度下的Ea;TLCP的加入加速了酚醛树脂固化反应,降低了酚醛树脂固化反应活化能,当TLCP的质量分数为10%时,Ea最小。

英文摘要：

The curing kinetics of thermotropic liquid crystalline polyester（TLCP）/phenol formaldehyde resin（PF）blends was studied by non-isothermal DSC.The curing kinetics of TLCP /PF blends and pure PF resins was compared and the effect of TLCP contents on the curing kinetics was investigated by three phenomenological models（including Ozawa and Kissinger simple models and Kissinger-Akahira-Sunose（KAS）isoconversional method）.The results showed that the activation energy（Ea）datas of the TLCP /PF blends calculated by Kissinger and Ozawa models were consistant.The Ea of TLCP /PF blends at different curing degree were calculated by KAS model.The addtion of TLCP accelerated the curing process of PF and reduced Ea.The Ea of TLCP /PF blends with 10% TLCP reached the minimum.
