采用化学分析用电子能谱技术(ESCA)分别对机械剥离后的玻璃纤维布和短切玻璃纤维增强环氧树脂试样的玻璃纤维(布)面作了对比分析,发现树脂残留物表面上有富裕的环氧基,证明剥离不是发生在树脂/玻璃纤维(布)粘结界面上,而是发生在粘结界面附近的树脂层里;环氧树脂/玻璃纤维布界面比环氧树脂/短切玻璃纤维界面有更强的界面增强效应.
By chemical analysis of electron spectroscopy (ESCA) were mechanical glass fiber cloth and chopped glass fiber reinforced epoxy resin sample glass fiber (cloth) made a comparative analysis of surface and found that the resin residue on the surface Affluent epoxies demonstrate that stripping does not occur at the resin / fiberglass (cloth) bonding interface, but rather at the resin layer near the bonding interface; the epoxy / fiberglass interfacial interface is less than the epoxy / short Cut glass fiber interface has a stronger interface enhancement effect.
