**Abstract**
 The use of DC electrical resistance measurement for the self-sensing of strain and damage in continuous carbon fibre polymer-matrix structural composites is examined. Carbon fibres, being electrically conductive enable composites to exhibit electrical properties which depend on parameters such as strain and damage, thereby attaining the ability to sense themselves through electrical measurement. A consequence of self-sensing structural materials is reduced cost, enhanced durability, a larger sensing volume, and an absence of mechanical property degradation.. This paper provides a review of self-sensing behaviour, in addition to addressing the design of the electrical contacts, and providing a model for relating the electrical resistance to the type and amount of damage. 37 refs.
