Title:
CARBON FIBRES, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/133514
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide carbon fibres which achieve a high elongation percentage and a high strand elastic modulus while being lightweight. Accordingly, these carbon fibres are configured such that: the void content in a cross section of the fibres in the axial direction, said cross section including the long axis of a cross section of the fibres in the radial direction, is at least 0.3% by area, but not more than 5.0% by area; the average aspect ratio of the voids is at least 2.0, but not more than 50; and the average width of the voids in the cross section of the fibres in the radial direction is at least 3 nm, but not more than 100 nm.
