Lamb Wave Propagation in Thermally Damaged Composites

Abstract

The use of composites in primary and secondary structures of aerospace vehicles is important for increased performance with little weight penalty. Determining the response to thermal damage is necessary for a complete understanding of the total use environment of these materials. The objective of the research presented here is to provide a method of quantifying the amount of thermal damage in composite materials. Components which have non-visible damage, but have degraded performance on the order of several percent, are of interest. At this level of damage the safety margin designed into the structure may be compromised.
