Examination Of Electrical Behaviour Of Unidirectional Epoxy-Carbon Fiber Composite Under Tensile Load By Experimental Method.

摘要

Composites are modern materials which are currently used in almost all areas of technology. Because of the versatile behaviour ofcomposites, analysis of composites is required to be done. In this work a unidirectional epoxy-carbon fiber reinforced composite was subjected to tensileload. While loading, the electrical resistance measurement is done using Kelvin’s four-wire method. Electrical contacts were made by epoxy-silveradhesive on the specimen. Connecting wires were attached with the epoxy-silver adhesive. The results obtained during tensile test were analysed tostudy the mechanical and electrical behaviour of the composite and their correlation which could be helpful in predicting the performance of compositematerials.
