中文名称：碳纤维 长丝直径和横截面积的测定
英文名称：Carbon fibre — Determination of filament diameter and cross-sectional area
发布日期：2018-08
标准范围
This document specifies five test methods used for the determination of the diameter and cross-
sectional area of single carbon fibre filaments.
The shape of the cross-section of the filaments from different suppliers can vary significantly. The term
“diameter” used in this document applies to all cases, from a “true” diameter, where the filament is
exactly circular in cross-section, to an “apparent” diameter where the filament is not circular.
The methods proposed are not necessarily directly applicable to all types of filament. The product
specification determines the method to be used. If there is no specification, the selection of the
appropriate method is a matter of judgement. The details given here are considered to be sufficiently
precise to enable this choice to be made.
