Abstract

The repair technique of the composite patch with bonding adhesive are used with the purpose of repairing materials and increasing working life of the materials. In this study, the impact strength of notched metal materials repaired by composite patch investigated by numerically. Fiber reinforced laminated composite patch was modeled by using finite element model. Composite patch was bonded to damaged materials, and this structure was subjected to impact test. The geometrical and material non-linearities were considered in the explicit dynamic analysis. The notched plate was made of aluminum 6061-T6. The effects of design parameters, such as composite patch geometry, on the impact energy absorption of the plates were investigated. The metal notched plates were modeled as a Johnson-Cook material model and the composite patches were modeled orthotropic elastic material model and Hashin damage. In the analysis results, the damage mechanisms of composite patch were exhibited and strength of damaged materials was exhibited in terms of contact force, kinetic energy and stress distributions. The effect of patch geometries was also investigated in terms of absorbing impact energies. As the plates without patch perforated, repaired metal notched plates with composite patch did not perforate.
