| Abstract: | The monitoring of wood-based materials damage evolution characteristics has always been a hotspot in wood science. Acoustic emission technology is a real-time and continuous monitoring technology, which has been widely used in the research on damage monitoring of wood-based materials. Focusing on the application of acoustic emission technology to wood damage monitoring, this paper summarizes the principle and analysis method of acoustic emission technology, concludes the influencing factors that wood-based material characteristics have to acoustic emission signals, and discusses positioning of wood-based material damage source, damage monitoring of solid wood and wood-based composites, and development prospect. It is expected to provide a reference for the further application of acoustic emission technology to the field of wood-based materials. |
