The electroinitiated polymerisation of methyl methacrylate containing sulphuric acid was found to be localised at the surface of a cathode of carbon fibre. The influences of various reaction parameters on the rate of polymerisation and the molecular weight have been recorded but do not agree totally

Abstract
Polyacrylamide has been synthesised at the surface of carbon fibre by the technique of electropolymerisation. Some details of the polymerisation have been presented and a preliminary proposal made for the mechanism responsible. The characterisations of carbon fibre and its surface have always presented a problem; in this work torsional braid analysis has been used to study the polymer present on the surface of the fibre.

HT-fibres (Grafil XAS12K) were coated with thin layers of polydimethylsiloxane in order to prevent or diminish the adhesion of the phenolic resin to the fibre surfaces. The physical and chemical changes of the polydimethylsiloxane layer at various stages of curing and thermal treatment were studied
