The microstructure of polyacrylonitrile‐base (PAN‐base) type I and type II carbon fibres has been studied by X‐ray small‐angle and wide‐angle scattering. Recent work in this field is critically reviewed and it is shown that the structural model proposed by Johnson & Tyson for these types of fibre is inadequate. The microstructure of PAN‐base carbon fibres is essentially the same as that of rayon‐base carbon fibres. Differences appear only in the volume fraction occupied by the microvoids.
