This Web page contains a paper on "Non-contact ultrasonic techniques for process control of composite fabrication", written by B. Boro Djordjevic and Robert E. Green Jr.
The paper addresses the monitoring of the final consolidation process for both thermoset and thermoplastic composites.
The two parameters currently routinely monitored for these materials are the temperature and the pressure applied to the filaments, tows, or laminates. This is commonly achieved with conventional thermocouples and pressure gauges. A dielectric sensor mounted between two composite plys in autoclave curing which measures the ionic conductivity is also routinely used to monitor the cure process. Contact or water coupled ultrasonics, non-contact ultrasonics, laser ultrasonics and developing systems are discussed. Non-contact ultrasonic techniques for process control of composite fabrication are covered, along with a Bibliography.

Keywords: Research, Composites, Fabrication
Established in 1945, the Applied Research Laboratory conducts both basic and applied research and technology along with engineering development for scientific, industrial, and defence applications. The Applied Research Laboratory is a Navy-sponsored research facility to advance the Navy's technology base through research and development.
The mission of the Applied Research Laboratory is to serve as a centre of research excellence in undersea science and technology. For applications in marine vehicles it has earned itself a leadership role in the development of composite technology. To support this role, the Applied Research Laboratory has assembled an experienced technical staff, established complete in-house design/analysis, fabrication, and testing facilities, and has developed an extensive network of proven subcontractors.
Technology advancement has occurred in areas including active and passive noise and vibration control using advanced composite materials, development of fabrication techniques capable of producing laminated composite structural components greater than 8 inches thick, development of both strength-based and fracture mechanics-based fatigue test methodologies and life prediction models for complex geometry composite hardware, optimisation of low-cost fabrication techniques such as laminate winding and resin transfer molding for marine and industrial composite structures, and the development of advanced ultrasonic inspection and in situ acoustic emission monitoring techniques.
Overall, this is a very interesting site and is worth a visit.
