Abstract
Lamb waves are promising for Structural Health Monitoring (SHM) in plate-like components from carbon fiber-reinforced plastics (CFRP). They may be excited and received by plane piezoelectric actuators embedded or attached to the material. Several Lamb wave modes are known, among them the basic symmetric and anti-symmetric mode. Under certain circumstances these modes may convert into each other. This conversion may be used as an indication of defect presence and for defect characterization. The paper focuses on the conditions of Lamb wave conversion at defects and internal material structures. So, the cases of local defects as potential sources of mode conversion are regarded and the phenomenon of continuous mode conversion (CMC) in CFRP and current results of its characterization will be presented.
