Abstract
A method of bonding a first part on a second part made of composite material by an adhesive, in which the adhesive is filled with elements of shape memory alloy, is provided. A method of un-sticking the first part adhesively bonded on the composite material second part is also provided. The un-sticking method includes a step of weakening the adhesive interface that consists in subjecting the adhesively bonded parts to heat treatment performed at a temperature that is lower or higher than the martensitic transformation temperature of the shape memory alloy elements.
Claims12
A method of un-sticking a first part adhesively bonded on a composite material second part comprising:
- bonding the first part on the second part made of composite material by an adhesive layer, wherein said adhesive layer is filled with elements of shape memory alloy dispersed in said adhesive layer;
- and
- weakening an adhesive interface by subjecting the adhesively bonded parts to heat treatment performed at a temperature that is lower or higher than a martensitic transformation temperature of the shape memory alloy elements.
