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

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%.
