用X射线小角散射和广角散射研究了聚丙烯腈基（PAN基）Ⅰ型和Ⅱ型碳纤维的微观结构。最近在这一领域的工作进行了严格的审查，它表明，结构模型提出的约翰逊和泰森为这些类型的纤维是不够的。PAN基碳纤维的微观结构与粘胶基碳纤维基本相同。差异只出现在由微孔占据的体积分数。
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.
