摘要
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.
The electroscopy spectroscopy for chemical analysis (ESCA) has been applied to the analysis of the failure surfaces generated by the mechnanical delamination of epoxy/glass fiber cloth and epoxy/ short-cut glass fiber in contrast at the glass failure side. A complementary enhancement of epoxy was observed on the interfacial polymer residues surface, which is shown that failure ocuurs in the polymer layer close to, but not at, the polymer-glass interface. The epoxy/glass fiber cloth interface has much stronger reinforcing effect than the epoxy/short-cut glass fiber.
