Tensile Property and Influence Parameters of Bonded Repaired Composite Laminates
Bonded repair is efficient and widely-used repair technique for composite structures. Tests were conducted to study the tensile property of scarf repaired and external bonded repaired composite laminates with different repair parameters. The results show that the recovery of failure strength of scar...

When repairing in double sides, enlarging the size of patches, the external bonded repaired specimens can also reach a higher recovery rate of failure strength. Based on the test results, finite element models were established to predict the failure loads and failure modes of specimens, and to analyse the stress distribution and progressive damage process of specimens, which can provide a reference to the designing in the repair projects. |
