The European Defence Agency (EDA) project PATCHBOND II (June 2020 – June 2025) was established for studying adhesively bonded repairs of primary composite structures. This multinational project is based on collaboration between several aerospace companies, governmental institutions, research institutes and universities. The main targets are to study damage tolerance and monitoring of the bonded repairs of primary aircraft structures. The project is divided into four technical work packages, for which motivations and developments are presented. The on-going project work has already provided valuable results in the field of adhesively bonded repairs.
