Strain monitoring in composite patched structures
Source abstract
Abstract
Bonded composite patch repair is a developing technology that has been used in the aerospace industry for the purpose of improving the mechanical properties of structure. Graphite/epoxy and boron/epoxy have been the main composite patch materials used in current applications and these composites are bonded to the metallic substrate with epoxy based adhesives. For an effective adhesively bonded reinforcement of a plate, sufficient load must be transferred by the adhesive into the reinforcement to prevent the underlying damage from growing. In this paper, strain monitoring was studied in a single sided patched structure. The thermal residual strains were defined in graphite/epoxy composites on Al-2024 T3 substrate. Five samples were manufactured, and several strain gauges were bonded on the patch Al-substrate. Thermal and thermal residual strains were measured after one- and two-step curing at different temperature and the results were compared with each steps as well as previous work.
