发明名称 Method for assembling a piece of metal material to a piece of composite material
摘要 Process for assembling a first part made of metal material and a second part made of composite material, by an attachment element, which includes: -pre-piercing the parts to form a recess with a diameter D1 in the first and the second parts; -installing an insert having a variable diameter in the direction of the thickness of the parts in the recess, the insert including a main hollow body and at least one flange designed to rest at least partially against the outside surface of a part, the insert being designed to accommodate the attachment element; generating residual compression constraints by radial expansion on the inner wall of the insert by an expansion tool having an outside diameter that works with the inside diameter of the insert in at least one zone of the two parts along the circumference of the insert; -boring the recess of the main body wider so that the insert has a final inside diameter that is significantly greater than the outside diameter of the attachment element to allow play between the inner wall of the insert and the outside surface of the attachment element; and -positioning the attachment element in the insert to keep the parts together.
