Method for repairing a sound attenuation panel |
摘要 |
A method for repairing a sound attenuation panel is disclosed. The panel includes a structuring skin in metal material, a resistive layer in metal material and a honeycomb structure as acoustic absorption material directly added onto the structuring skin and resistive layer. The method includes a step in which one reinforcing pin is inserted into the thickness of the attenuation panel and a step in which the reinforcing pin is secured by welding in a controlled atmosphere to the structuring skin and resistive layer respectively. |

1. A method for repairing a sound attenuation panel comprising a structuring skin in metal material, a resistive layer in metal material and a honeycomb structure as acoustic absorption material directly added onto the structuring skin and resistive layer,
wherein the method comprises at least one step in which at least one reinforcing pin is inserted into the thickness of said sound attenuation panel, a welding step of providing on both sides of a welded surface with welding in a controlled inert atmosphere, and a step in which said at least one reinforcing pin is secured by welding in the controlled inert atmosphere to the structuring skin and resistive layer respectively. |
