Composite pipe

摘要

A pipe (70) having a pipe wall (72) comprises a composite material formed of at least a matrix (74) and a plurality of reinforcing fibres (76) embedded within a matrix (74). The matrix (74) defines a continuous structure and the fibres (76) are variably distributed within the continuous matrix structure (74). In one embodiment the fibres (76) are distributed radially throughout the continuous matrix (74) from zero at the region of the inner surface (78) of the pipe wall, and are increased in a direction towards the outer wall (80).
