Abstract
Ultrasonic techniques were used to monitor flaw growth in graphite/epoxy laminates containing four types of initial flaws and subjected to fully reversed spectrum fatigue loading, including temperature and moisture variations. The initial flaws investigated were: circular hole, embedded film patch, internal ply gap and surface scratches. The specimen gage section was 5. 08 cm long and 3. 81 cm wide. In general, it was found that flaw growth was much more pronounced in the specimen exposed to environmental fluctuations in addition to the load spectrum, than in those tested in an ambient environment.
