Numerical modelling of resistance changes in symmetric CFRP composite under the influence of structure damage
چکیده انگلیسی

CFRP (Carbon Fibre Reinforced Polymer) composite consists of two materials characterised by different electric properties i.e., carbon fibres – the high strength component with conductive features as well as polymer fillers with insulating properties. For this reason, any structural damage will result in changes in electrical properties of the whole composite. This paper presents a mathematical FEM-based model allowing for simulation of damage in monolayer symmetric laminate structure. The dependences of electrical responses on the size and location of damage as well as the sensitivity of the method for accurate placement of electrodes supplying electric current were investigated. The effectiveness of this method for determining the approximate size and location of the damage and the usefulness of the FEM for modelling the changes in electrical properties of the composite were demonstrated.
