低温等离子体处理对芳纶界面性能的影响

Influence of low temperature plasma treatment on surface performance of aramid fibers

为研究低温等离子体处理对芳纶界面性能的影响,制作了满足要求的试样并进行等离子体处理实验。采用扫描电子显微镜(SEM)、浸润性实验等方法对芳纶表面的刻蚀程度进行表征,并对低温等离子体处理前后的芳纶进行拉伸性能测试。结果表明:随着低温等离子体处理时间的延长、处理功率的增大,芳纶表面刻蚀程度加剧;低温等离子体处理后芳纶的拉伸性能变化不大,但纤维的浸润性有了明显改善;纤维与树脂的结合强度也有近50%的提高。

To study the influence of low temperature plasma treatment on the surface performance on aramid fibers,samples were made and plasma treatment of the samples was performed.The degree of plasma etching on the surface of aramid fibers were characterized with scanning electron microscopy（SEM） and hydrophilicity tests,and tensile strength of aramid fibers before and after low temperature plasma treatment was tested.The results showed that the degree of plasma etching on the surface of aramid fibers increased with the increase of treating time and power.The tensile strength of aramid fibers after low temperature plasma treatment showed little change,but hydrophilicity of the fibers improved significantly,and their adhesion strength with resin increased by nearly 50%.
