Abstract
The inability to detect impact damage in composite material structures is a major factor blocking more extensive use of these materials. Past research utilizing a simplistic measurement of AU has indicated great potential when used in a laboratory environment. The use of AU outside of the laboratory by non-scientists has not met with the same success. This report describes the use of a more complicated approach to AU which incorporates several parameters measured simultaneously. The result is a technique, called “DCAT” (Dry Contact Acoustic Transmission; Patent Pending), which can be utilized to locate impact damage in non-laboratory environments.
