碳纤维增强热塑性塑料（CFRT）复合材料具有轻质、高强等上级性能，在汽车领域得到了广泛的应用。自电阻电加热（SRE）技术解决了碳纤维增强复合材料传统工艺能耗高的问题。利用X射线光电子能谱（XPS）研究了SRE加热对碳纤维（CF）表面化学性质的影响。XPS分析表明，强电流SRE加热后，CF表面的C-O-C环氧基发生降解，而-C-OH、-C-O-C-、-C-NH 2和-COOH基团的含量随电流强度的变化很小。采用分子动力学（MD）模拟方法研究了碳纤维（CF）与聚丙烯（PP）的界面结合性能和界面径向分布函数（RDF）。模拟结果表明，PP与E44浆料之间的粘附力弱于CF与PP之间的粘附力。PP与E44施胶剂之间除静电吸附和货车范德华力作用外，无其它作用方式。E44施胶剂的存在不改变CF/PP界面的粘结机理。
Carbon fiber-reinforced thermoplastic (CFRT) composites have been dramatically employed in the automotive field on account of their superior performances, such as being light weight and high-strength. Self-resistance electric (SRE) heating provides a solution to the problem of high energy consumption in the conventional process of CFRT composites. The effect of SRE heating on the surface chemical properties of carbon fiber (CF) was investigated by X-ray photoelectron spectroscopy (XPS). XPS analysis suggests that the C-O-C epoxy group, the CF surface, would be degraded after SRE heating with strong current intensity, while there are weak changes in the content of -C-OH, -C-O-C-, -C-NH2 and -COOH groups with current intensity. The interfacial bonding properties and the radial distribution function (RDF) of CF–PP interfaces were carried out by molecular dynamics (MD) simulation. The simulation results show that the adhesion between the PP and the E44 sizing agent is weaker than that between CF and PP. There are no interaction modes between the PP and E44 sizing agent except van der Waals and electrostatic adsorption. The presence of the E44 sizing agent does not change the bonding mechanism at the interface of CF/PP.
