摘　　要：以改性环氧树脂为主体树脂制备了国产高温湿可剥布。通过拉伸剪切强度和浮辊剥离强度等测试,对湿可剥布与国产固化预浸料固化工艺的匹配性进行了研究。结果表明,高温湿可剥布适用于国产树脂固化工艺。采用该湿可剥布与国产预浸料匹配使用,并进行了粘接性能研究发现拉伸剪切强度≥20 MPa,浮辊剥离强度≥25 N/cm,夹层件平面拉伸强度≥1.9 MPa。A domestic wet peel ply is prepared with epoxy resin as the matrix resin.The matching of wet peel ply and domestic prepreg curing process is studied through tensile shear strength and floating roller peel strength test.The results show that the wet peel ply is suitable for the curing process of domestic resin.The adhesion performance of domestic prepreg using with the prepared wet peel ply is studied,and it is found that the tensile shear strength is over 20 MPa,the floating roller peel strength is over 25 N/cm and the flatwise tensile strength of sandwich part is over 1.9 MPa.
