An Embedded Ultrasonic Wire Waveguide Sensor for In-Process Cure and In-Service Dynamic Response Monitoring of Liquid Molded Composite Parts

Over the last decade, liquid molding techniques have become more and more popular for manufacturing of composite parts and structures. These techniques are often selected due to the ease of manufacturing automation and the ability to effectively and inexpensively produce large and complex shaped parts and structures. Resin transfer molding (RTM), vacuum assisted RTM (VARTM) and Seemann’s composite resin infusion molding process (SCRIMP) are examples of widely applied liquid molding techniques in the composite industry today.
