| 摘 要： | 为了提高环氧涂料在纤维增强聚丙烯复合材料上的附着力，采用激光和等离子体表面前处理方法，应用超景深显微镜、粗糙度测定仪、接触角测试仪以及附着力测试仪，研究了激光和等离子体表面处理对纤维增强聚丙烯复合材料表面形貌、表面粗糙度和表面水接触角的影响，并且探究了这 2种表面处理方式对环氧涂层在复合材料上附着力的影响。结果表明： 2种处理方式均可明显提高环氧涂层在基材上的附着力，附着力均可由不到 1 MPa提高至 8 MPa以上。

| Abstract: | In order to improve the adhesion of epoxy coatings on fiber reinforced polypropylene composite material，laser and plasma surface treatment methods were used. The effects of laser and plasma surface treatment on surface morphology，surface roughness and contact angle of fiber reinforced polypropylene composite were studied in detail with hyperfield microscope，roughness tester，contact angle tester and adhesion tester . The effects of these two surface treatments on the adhesion of epoxy coatings on composite was also investigated. The results showed that the adhesion of epoxy coatings on the substrates could be significantly improved by both treatments，from less than 1 MPa to higher than 8 MPa. |
