Abstract
The main objective of the present work was to study the low-velocity weight-drop impact damage behaviour of carbon – carbon silicon carbide (C/C– SiC) composites on electrical resistivity of the direct-current potential drop method. The results show that the electrical resistivity increases with increasing impact energy, which confirms that pre-microcracks of C/C– SiC composite grow very rapidly with a little amount of impact load and turn into a loss of conductivity of the material.
