An X-Ray Photoelectron Spectroscopic Examination of Surfaces of Some Thermosetting Resins and Carbon Fibre Composites.

Abstract

The surfaces of a range of cast thermosetting resins and carbon fibre composites have been investigated by electron spectroscopy for chemical analysis (ESCA). The peaks recorded were asymmetrical and could be resolved to give minor peaks which were related to the chemical groups present in the resins. In particular, peaks due to the CF2 group were deconvoluted from the carbon 1s and fluorine 1s peaks and related quantitatively. These groups arose from contamination of the resin and composite surfaces by polymeric fluorinated hydrocarbon release agents. Surface contamination was reduced to a low level by abrasion. Oxidative chemical treatment of composite surfaces caused an increase in the amount of oxygen bonded to carbon. (Author)
