| Abstract: | With excellent electricity conducting property, the carbon fibers in carbon fiber reinforced composites can form electricity conducting network by contacting each other. Under the effect of external load, carbon fiber reinforced composites are often damaged by lamination or fracture of fibers, resulting in the change of electricity conducting network and resistance. In the present work, the electricity conducting theories and relevant calculation models of carbon fiber reinforced composites, as well as the studies on resistance change of carbon fiber reinforced composites under loading were introduced and summarized. In addition, the disadvantages and trends of the studies on the electricity conducting properties of carbon fiber composites were pointed out. |
