Title:
STRATIFIED ALUMINIUM-COMPOSITE HYBRID PART
Document Type and Number:
WIPO Patent Application WO/2019/186021
Kind Code:
A9
Abstract:
The invention relates to an aluminium-composite hybrid part comprising a stack of layers formed by alternating metallic layers made of an aluminium alloy and composite layers, characterized in that at least one of the layers is a metallic layer that is less than 1 mm thick and is made of an aluminium alloy, referred to as alloy of interest, belonging to the 6xxx series and containing between 0.6 and 1.5 % by weight silicon and between 0.4 and 1.2 % by weight magnesium, the percentage by weight of silicon being greater than that of magnesium. The invention also relates to an aircraft structural element comprising at least the above aluminium-composite hybrid part, and to a method of producing said aluminium-composite hybrid part, which includes at least one step of machining at least one layer made of the aluminium alloy of interest until it is less than 1 mm thick.
