ABSTRACT: The paper focuses on the importance of using specific values (values where the axial property is normalised by dividing by density) for properties of CNT yarn-like fibres to avoid the huge uncertainties introduced by the state of lateral compression of the yarn, a difficulty not only associated with the measurement of cross sectional area, but exacerbated by the influence of winding forces and indeed gripping forces while under test. Even with the disciplined use of specific parameters, there are also serious issues regarding axial mechanical tests and measurements of thermal conductivity. These are discussed as well.
