Abstract
Adaptive Werkstoffsysteme auf der Grundlage carbonfaserverstärkter Laminate mit integrierten piezokeramischen Sensoren und Aktuatoren sind aussichtsreiche Komposite bei der Schwingungs- und Lärmdämpfung. Wegen der großen Bandbreite der physikalischen Eigenschaften ihrer Komponenten können spezifische Schädigungsmechanismen die sensorischen und aktuatorischen Wirkungen reduzieren. Die umfassende zerstörungsfreie Charakterisierung und das Health Monitoring leisten einen wesentlichen Beitrag bei der Entwicklung geeigneter Herstellungsverfahren und zur Strukturüberwachung. Adaptive material systems and their non-destructive characterisation Smart materials based on carbon fiber-reinforced plastics with embedded piezoceramic sensors and actuators are expected to be a favorite composite for vibration damping and noise reduction. Due to the wide variety of physical properties of the components various damage mechanisms may reduce the sensing and actuating capabilities of the piezoceramic material. Comprehensive non-destructive characterization and integral health monitoring help to optimize the structure and its manufacturing and are an essential prerequisite to ensure performance and availability of smart components during their life time.
