A vibration-powered CFRP composite with piezoelectric nanomaterials detects internal cracks via electrical changes, enabling self-powered, wireless structural health monitoring. (Nanowerk News) A new multifunctional composite made of carbon fiber-reinforced polymers (CFRP) and piezoelectric materials can use vibrations to self-detect tiny cracks. This material could be used in the aerospace, automotive, and construction industries to monitor structural health without the need of an external power source.
