Griffith Equation and Carbon Fibre Strength

Abstract

ALTHOUGH the strength of carbon/graphite fibres is known to depend partly on surface and internal flaws, some of which originate in the precursor fibres1,2, several other strength controlling mechanisms and parameters have been proposed, including plastic yielding and dislocation pileup3,4, inter-fibrillar cross-linking4,5, and three-dimensional crystals of graphite6. There is no direct experimental proof of any of these hypotheses, however.
