Low Velocity Impact Behaviour of Damaged Composite Plates Repaired by Composite Patches
Journal Title: Mehmet Akif Ersoy Üniversitesi Uygulamalı Bilimler Dergisi - Year 2019, Vol 3, Issue 1
Abstract
Adhesive bonding technique is used in many engineering applications. Repairing with fiber composite patches using adhesive bonding technique are widely used for repairing cracks or other defects. Patch application to damaged materials with adhesive bonding is used to extend the service life of the material. In this study, patches were bonded damaged fiber-reinforced laminated composite plates and the dynamic load resistance was investigated numerically. Damaged composite plates and fiber reinforced composite patches are bonded with adhesive. Non-linear finite element analyses were performed in the ABAQUS finite element software. A cohesive zone model based on fracture mechanics was used as the adhesive material model. Low velocity impact behavior of damaged plates repaired by composite patches was also investigated for different patch material such as aluminum and fiber reinforced composite. Impact analyses performed on different impact energy with constant impactor weight were investigated in terms of contact force variations, kinetic energy variations and impact damage. Damaged plates without patch were perforated and damaged. Composite patches absorb impact energy and prevent the perforation.
