采用对相互作用能分解（PIEDA）方法研究了环氧树脂与碳纤维的粘接，将粘接相互作用能和粘接力分解为静电能、交换排斥能、电荷转移能和货车色散能。三个稳定的静电，电荷转移和分散的影响与不稳定的交换排斥效应。碳纤维的表面结构由石墨的基面、扶手椅边缘结构和OH官能化的扶手椅边缘结构来模拟。α-方石英表面（覆盖有OH基团），这可以被看作是一个很好的模型的亲水性玻璃表面，也进行了研究。模型接口的粘合性能的基础上的树脂与碳和玻璃表面的结合能和粘合力作用在界面上的能量分解进行评价。PIEDA计算表明，...
The adhesion between epoxy resin and carbon fiber is investigated by using pair interaction energy decomposition analysis (PIEDA), by which the adhesive interaction energy and adhesive force can be partitioned into the electrostatic, exchange-repulsion, charge-transfer, and van der Waals (dispersion) contributions. The three stabilizing electrostatic, charge-transfer, and dispersion effects are correlated with the destabilizing exchange-repulsion effect. The surface structures of carbon fiber are modeled by the basal face, the armchair-edge structure, and the OH-functionalized armchair-edge structure of graphite. The surface of α-cristobalite (covered with OH groups), which can be viewed as a good model of a hydrophilic glass surface, is also studied. Adhesive properties of the model interfaces are evaluated on the basis of the binding energy of the resin with the carbon and glass surfaces and the adhesive force acting at the interfaces in terms of energy decomposition. PIEDA calculations demonstrate that...
