摘要

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。

Abstract: 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.
