Abstract
Recent advances in milling technology have made it possible to produce an extremely short carbon microfibre which retains all of its mechanical properties and the filament’s shape. Use of such a short fibre enables a substantial amount of it to be incorporated into a polyphenylene sulphide protective coating for use on steel. The emphasis of the current study is to assess the effectiveness of this milled carbon microfibre in enhancing further the thermal conductivity and the mechanical properties of the carbon fibre-reinforced PPS composite coating. Results of tests showed that the composite coatings were able to protect underlying carbon steel against corrosion in 250 degrees C carbon dioxide-laden brine. The reason for the hydrothermal stability is reported to be conformational changes in the molecular structure of the PPS, from sulphide bridging to sulphone bridging, which increased the thermal stability of the matrix. 9 refs.
