摘要

以QZ5526碳纤维为研究对象,通过调整凝固浴参数制得腰形和圆形2种截面形状的QZ5526碳纤维,并对腰形和圆形QZ5526碳纤维的截面形状对表面活性的影响进行分析。研究结果表明:截面形状对纤维表面活性影响较小,腰形和圆形2种截面形状的QZ5526碳纤维的表面形貌相似,表面粗糙度分别为35.9nm和36.0nm;表面氧元素含量分别为8.04%和8.14%,氮元素含量分别为3.05%和2.80%,差别较小;表面自由能分别为23.67Nm/m和23.25Nm/m,其中极性自由能分量分别为6.13Nm/m和5.75Nm/m,表明腰形和圆形截面形状纤维与基体树脂的相容性相当。
        The carbon fiber of domestic QZ5526 was studied.QZ5526 with cross section of waist and circular shape were prepared respectively by adjusting coagulation bath parameters,and the influence of waist and circular shape cross section of QZ5526 on the surface activity was analyzed.It was found that there were less affected between surface activity and cross section shape,and the surface topography of fiber with waist and circular shape were similar,the surface roughness were 35.9 nm and 36.0 nm,the content of oxygen on the surface was 8.04% and 8.14%,and the content of nitrogen was 3.05% and 2.80%,respectively.The surface free energy was 23.67 Nm/m and 23.25 Nm/m respectively,of which the polar free energy component was 6.13 Nm/m and 5.75 Nm/m respectively,indicating that the fibers with waist and circular cross-sectional shape were compatible with the matrix resin.
