摘要
为了提高涤纶纤维在复合材料中与树脂基体的界面粘结性,使用等离子体技术对高强涤纶纤维进行表面改性。通过设计正交试验,得出等离子体处理高强涤纶的最佳条件为放电功率150 W,处理时间300 s,放电压强10 Pa。采用扫描电子显微镜、傅里叶变换红外光谱、纤维接触角测量仪、电子单纤维强力机和纤维摩擦系数测定仪对改性前后高强涤纶纤维进行性能表征。结果表明:改性后的涤纶纤维,其断裂强力较原样下降了1.78%,静摩擦系数上升了21.9%,纤维接触角下降了27%,且红外光谱图显示经过等离子体物理改性,引入了少量亲水基团,且未对纤维内部的基本分子结构造成破坏。
In order to improve the interfacial adhesion between polyester fiber and resin matrix in composite materials,plasma technology was used to modify the surface of high strength polyester fiber.Through the design of orthogonal experiment,the best conditions were defined as follows:discharge power 150 W,treatment time 300 s and discharge pressure 10 Pa.The properties of high strength polyester fiber before and after modification were characterized by scanning electron microscope,Fourier transform infrared spectroscopy,contact angle measuring instrument,electronic single fiber strength tester and fiber friction coefficient measuring instrument.The results showed that the breaking strength of the modified polyester fiber decreased by 1.78%,the static friction coefficient increased by 21.9%,and the contact angle of the fiber decreased by 27%,and the infrared spectrum showed that after the plasma physical modification,a small amount of hydrophilic groups were introduced,and the basic molecular structure of the fiber was not damaged.
