Abstract
The surface of six commercial carbon fibre qualities has been dtudied, three from Courtaulds and three from Torayca. These carbon fibres can be divided into three groups: Type 1 Courtaulds HM-S and Torayca M 40A; Type 2 Courtaulds HT-S and Torayca T 300A; and Type 3 Courtaulds A-S and Torayca T 200A. The surface studies based on high-energy photoelectron spectroscopy and Auger electron spectroscopy show that the oxygen concentration (atomic %) in the surface ranges from 30–50%. Silicon is detected only on the outermost layer of the fibre surface and probably originates from the surface treatment of the carbon fibres. The Auger spectroscopy examination gave concentration gradients for oxygen, sulphur and chlorine and indicates that the sulphur and chlorine atoms are bonded between the graphitic basal planes in the fibres.
