摘要
利用XPS研究了瞬时高温空气氧化法和气液双效法表面处理炭纤维的表面氧含量和含氧官能团的变化。表明，经表面处理后，炭纤维表明氧含量增加。羧基减少，但羰基或羟基的增加增强了CFRP界面的粘结情况，提高了CFRP的层间剪切强度。并对上述两种方法进行了比较。发现羟基是增强CFRP界面粘结强度的主要基因；羰基可能是增强CFRP断裂韧性的基因。
The change of the content of oxygen and oxygen -containing functional groups of PAN-CF treated by instant air oxidation and GLDE method are studied by XPS. The two kinds of surface treatment methods are compared. It is indicated that the content of oxygen of treated CF surface is increased. The content of carboxyl groups are decreased,but that of carbonyl and hydroxyl groups are increased. The value of ILSS of CFRP is improved. Hydroxyl groups are main groups which can improve adhesion and bonding between CF and resin matrax. Carbonyl groups may improve tourhness of CFRP.
