Information

The purpose of this conference was to bring together workers actively engaged in, or interested in, composite design and manufacture, composite use, and NDE, to exchange latest state-of-the-art information. The objective of the conference was to provide a forum for technical presentations and exchange of ideas on technology developments that may lead to potential and/or significant advances in process control of composite fabrication. Information resulting from this conference is expected to be useful in reducing the cost and increasing the affordability of composites, and improving the quality of fabricated parts.

Primary topics covered include:

Composite Design, Fabrication, and Analysis
In-Line Process Control for Composite Manufacturing
NDE Sensors for Composite Monitoring and Inspection
Composite Manufacturing Process Automation
On-Line NDE Applications
