Abstract

Watt, Phillips and Johnson1 have reported the development of high strength, high modulus carbon fibres. More recently, Moreton, Watt and Johnson2 have reported the variation of the tensile properties of these fibres with their heat treatment temperature. Shindo3 did pioneer work on this class of fibre, including X-ray and electron diffraction and transmission electron microscopy on broken fragments, but he gave no clear picture of the structure within the fibre. This communication reports the results of our initial structural studies of fibres prepared by a similar process to that of Watt, Phillips and Johnson. These fibres, with diameters in the range 6–8µ, had been heat treated to 2,600° C and had moduli of 60 × 106 lb./in.2 and ultimate tensile strengths of 0.25 × 106 lb./in.2.
