<p>Plastics materials and articles containing uniformly distributed electrically conductive fibres at very low concentrations are described together with specific intermediate plastics products useful in the manufacture of such materials and articles. The process for producing such electrically conductive plastics material comprises the steps of: (a) providing a fibre/plastic composite having a conductive fibres content of from 20 to 70 volume percent and having a substantially parallel fibre arrangement therein, (b) admixing the composite with a predetermined volume of further plastics material, and (c) heating the mixture and working while maintaining low shear conditions to avoid excessive breakage of the fibres but sufficient to distribute the fibres uniformly within the plastic.</p> |
