本文研究了碳纤维经不同气氛冷等离子体处理后,其复合材料层间剪切强度的变化情况.并通过对处理前、后的高强碳纤维进行ESCA、Roman、TG、DTA 分析,提出了树脂基碳纤维复合材料的层间剪切破坏主要是发生在抗剪能力较弱的碳纤维表面层中.等氧离子体(O_2-PLasma)处理通过改变碳纤维的表面层结构,提高了表面层的抗剪能力.因此,其复合材料的层间剪切强度(ILSS)得到了大幅度提高.
In this paper, the change of interlaminar shear strength of carbon fiber treated by cold plasma in different atmosphere was studied, and the ESCA, Roman, TG and DTA analyzes of high-strength carbon fiber before and after treatment were presented. The interlaminar shear failure of composite mainly occurs in the surface layer of carbon fiber with weak shear strength.O_2-PLasma treatment improves the surface shear strength by changing the surface structure of carbon fiber. Therefore, the interlaminar shear strength (ILSS) of the composites has been greatly improved.
