Automated Honeycomb Composite Structure Repair System

Aerospace industry is facing a major challenge with structural behavior of the advanced composites. This is because of the inherent complex damage behavior of the composite material. The aircraft with continuous maintenance of structural integrity will have satisfactory performance. Honeycomb Sandwich panel is a widely used composite structure in various application. It is important that honeycomb sandwich panel repairs be made according to the best available techniques because improper repair techniques can pose an immediate or potential danger. The reliability of an aircraft depends on the quality of the design and the workmanship of the repairs. Complication occurs with the design of honeycomb panel as the structure should be as light as possible. Manual fixing of honeycomb sandwich boards take additional time and cost and furthermore some of the time prompts loss of basic respectability because of human mistakes So as to lessen the time and cost of fixing the honeycomb composite structure a robotized framework can be planned. Automated system includes drilling the damaged part without making more damages in panel, cleaning the wastage using the vacuum pump and filling the holes using chemical filler. These processes are controlled by micro controller using drivers. It will be useful in improving repairing techniques of sandwich structures.
