摘　　要：利用碳纤维布外贴的方式增强聚丙烯板材的抗冲击性能,为制备出性良好且碳纤维布不易脱粘的复合板材,设计出了环氧树脂粘贴工艺、环氧树脂粘贴打孔工艺、PP胶粘贴工艺和混合粘贴工艺,并对不同制备工艺下的复合板材分别进行了4、8、12 J的落锤试验。结果表明:在不同冲击能量下,混合粘贴工艺的方式对聚丙烯板材的荷载的提高效率最高,同时能够有效限制复合板材的变形,且试验后碳纤维布与板材间无脱粘现象,板材可进行二次冲击,是较佳的工艺方式;树脂粘贴打孔工艺虽然能够有效限制聚丙烯板材的变形,但其试验后碳纤维布与板材间脱粘现象明显,不可进行二次冲击,其工艺方式还需进一步改进。In this paper,the impact resistance of the polypropylene sheet is enhanced by the outside pasting way of carbon fiber cloth.In order to prepare the composite sheet with good properties and carbon fiber cloth is not easy to break off,the epoxy resin sticking process,epoxy resin sticking punching process,PP adhesive sticking process and mixed sticking process are designed.The 4,8 and 12 J drop weight tests were carried out on the composite plates under different preparation processes.The test results show that under different impact energy,mix-and-paste technology has the highest efficiency to improve the load of polypropylene sheet,and can effectively limit the deformation of composite sheet,and there is no debonding phenomenon between carbon fiber sheet and sheet after the test,and the sheet can carry out secondary impact,which is a better process.However,although the resin paste drilling technology can effectively limit the deformation of polypropylene sheet,the debonding phenomenon between the carbon fiber sheet and the sheet is obvious after the test,and the secondary impact cannot be carried out,so the technology method needs to be further improved.
