Abstract
SINGLE carbon fibres 25 cm long have been strained at a rate of 0.1 cm/h and their electrical resistance monitored continuously. Three different grades of fibre, each from a different source, have been studied (Table 1); values of Young's modulus were determined from tensile tests on individual fibres. The electrical resistance of the unstrained fibres varied from fibre to fibre even among fibres of the same grade. The variations within the grades appeared to be due to variations in the diameter of the fibres; mean values of resistance and diameter are given in Table 1.
