Experimental investigation of fatigue destruction of CFRP using the electrical resistance change method

Jacek Gadomski , Paweł Pyrzanowski


CFRP (Carbon Fiber Reinforced Polymer) composites are one of the most popular compos- ites used as the structural material in high-loaded structures. Important disadvantage of this material is the difficulty in predicting the time of fatigue destruction. These changes decrease the stiffness of the structure, but in practice it is usually not possible to measure it. Therefore, it is necessary to find another method to determine the moment when destruction of the composite begins. In this paper, one of possible methods – measuring of the electrical resistance change was investigated. Bending beam-shape specimens were tested under static and periodically varied load. Bending moment, deflection in the center of the probe and 8 voltages were measured. Performed experiment shows that measuring of the electrical resistance change provides better information about destruction of CFRP structure than a measure of the bending moment.
