The Effect of Neutron Irradiation on the Structure and Mechanical Properties of Carbon Fibres,

Abstract

The effect of fast neutron irradiation on the mechanial and microstructural properties of carbon fibres heat treated to various stages of graphitization has been investigated. Changes in selected crystallinity parameters were used to monitor the microstructural disorder induced in each fibre by three different irradiation doses. Associated changes in fracture strength and Young's modulus are related to the dependence of dislocation mobility on short range microstructural damage.
