等离子体改性技术在碳纤维/PEK-C复合材料中的应用研究
Study on the Application of Plasma Modification to Carbon Fiber/PEK-C Composites
摘要
Abstract
Surface modification of carbon fibers was conducted using a cold oxygen plasma technique. The surface of the carbon fiber was analyzed by X-ray photoelectron spectroscopy and atomic force microscopy. The effects of plasma power and treating time duration on the interfacial bonding properties and the mechanical properties of carbon/PEK-C composites were studied. The results show that the content of oxygen-containing groups and the roughness of the fiber surface are improved by the plasma treatment. Moreover, the interfacial bonding properties of the composite are strengthened. The primary failure mode of the carbon fiber/PEK-C composite under applied stress shifts from interface failure to matrix fracture after oxygen plasma treatments. When the carbon fiber is treated for 12.5 min with a plasma power of 200 W, the ILSS (the interlaminar shearing strength) and flexural strength of the composite reach to their maximum values of 94.12 MPa and 1316.76 MPa, respectively.关键词
