<p>A moulding material for forming tubes of fibre reinforced resins comprises a central tube substantially impervious to fluid pressure, at least one matrix resin tubular layer, and at least one reinforcement fibre tubular layer, each of which layers is substantially separate, the resin and fibre layers alternating and located co-axially about the central tube. The material can be formed and moulded without disturbing the arrangement of the fibres.</p> |
