Modeling of Electrical Resistance Measuring Method for Sensing Damage and Deformation in CFRP Composites

Popis výsledku v původním jazyce

This paper presents a study on electrical resistance (ER) measurement on unidirectional CFRP composite beam during cyclic flexural loading. ER measurement was conducted in the transverse direction to the fiber direction. Three measuring configuration, each in two copies were measured during shutdowns of loading. One measuring point was monitored by ER measurement also during cyclic loading. Artificial damage was created in a form of a cut in the middle of a specimen so that the cross section of the specimen was reduced. According to performed measurements further tests on possibility of damage detection during cyclic flexural loading by measuring ER in transversal direction must be performed. Possibility of fiber crack detection by presented type of measurement was confirmed.
