摘要
针对微波固化工艺下的碳纤维(T800)/环氧树脂复合材料的固化反应行为,运用非等温差示扫描量热(DSC)法,研究了T800/环氧树脂复合材料的固化反应放热过程。基于Kamal动力学模型,采用粒子群全局优化算法,拟合得到了纯微波固化工艺及高压微波固化工艺的T800/环氧树脂复合材料固化反应动力学方程,通过实验验证,该方程能够很好地描述T800/环氧树脂复合材料微波固化反应动力学行为。并系统对比研究了不同固化工艺方法对T800/环氧树脂复合材料固化反应动力学的影响。结果表明:相比传统热固化工艺,微波固化工艺能够有效提高T800/环氧树脂复合材料的固化反应速率并降低其固化反应的活化能,同时固化压力的引入对T800/环氧树脂复合材料的固化反应有一定的促进作用。
In order to investigate the curing behavior of carbon fiber（T800）/epoxy matrix composites under microwave curing process,the exothermal process of curing reaction of T800/epoxy resin matrix composites was studied by nonisothermal differential scanning calorimetry（DSC）.Based on Kamal dynamics model,T800/epoxy resin composite reaction kinetics equation of microwave curing technology and high-pressure microwave curing process was obtained by fitting the particle swarm optimization algorithm.And the effect of different curing methods on the curing kinetics of T800/epoxy resin composite was systematically compared.The experimental results show that the equation can well describe the microwave curing behavior of T800/epoxy resin composites.The results show that compared with the traditional thermal curing process,the microwave curing process can effectively improve the curing rate of T800/epoxy resin composite and reduce the activation energy of the curing reaction,while the introduction of curing pressure to the curing reaction of T800/epoxy resin composite have a certain role in promoting.
