| 摘 要： | 为了提高碳纤维表面的粘附能力,对活性烯类单体双丙酮丙烯酰胺(DAA)以及与丙烯酸(AA)组成的双组分体系在碳纤维表面的电聚合反应进行了研究.测定了经过电聚合的碳纤维制成的复合材料层板(CFRP)的层剪强度(ILSS),分别由未经处理的45.5MPa提高到70.36MPa和81.24MPa.对电聚合反应机理以及电聚涂层作为纤维/基体的中间层的缝合作用进行了讨论.单体溶液中加入自由基捕捉剂电聚涂层的形成严重受阻,这个现象证明DAA电聚合机理是自由基聚合反应.

| Abstract: | The electropolymerization (EP) of diacetong acrylamide (DAA) and acrylic acid/DAA on Carbon fiber Surface and the effects of EP coating upon performance of Epoxy unidirectional CFRP were studied . The shear strength of CFRP was significantly improved from 45.57 MPa to 70.36 MPa and 81.24 MPa respectively . The mechanism of EP and bridge function of EP coating as an intermediate between carbon fiber and epoxy matrix were discussed . When radical capturer was added into the monomer solution , the formation of EP coating was strongly retarded . This phenomenon implicated DAA EP mechanism may be free radical polymerization. |
