CARBON FIBER AND ITS PRODUCTION |
摘要 |
Disclosed are polyacrylonitrile carbon fibers excellent in substrate strength and adhesion to matrix resin wherein average nitrogen content in the whole carbon fibers which is measured by elementary analysis is 0.5-4.5% by weight and average nitrogen concentration (N/C atom number ratio) in the whole carbon fibers which is measured by elementary analysis and surface silicon concentration (Si2p/C1s atom number ratio), surface nitrogen concentration (N1s/C1s atom number ratio) and surface oxygen concentration (O1s/C1s atom number ratio) which are measured by X-ray photoelectron spectroscopy satisfy the following formulas: 0</=Si2p/C1s</=0.02 0.67 N/C+0.08</=O1s/C1s-2 Si2p/C1s</=0.4 0</=N1s/C1s-N/C</=0.04 and method for producing the carbon fibers. |
