Abstract
The potting failures of inserts in a sandwich structure are analyzed. The case of inserts potted with syntactic foam is investigated. First, the influence of defects is discussed. Then, experiments are performed to determine the tension and compression behavior of the syntactic foam. Later, a specific technological pull-out test was performed, while a Digital Image Correlation (DIC) system was used to record the tests. This allowed the different potting failure modes of inserts for sandwich panels to be observed and understood. The results obtained suggest that the potting failure of inserts occurs predominantly when fabrication or installation defects are present.
