Abstract
First and second aircraft structures are bonded together with an adhesive including strain-sensitive magnetostrictive material.
Claims13
A method comprising measuring strain in a joint between first and second aircraft structures bonded together with an adhesive, the adhesive including at least one of strain-sensitive magnetostrictive particles, a scrim made of strain-sensitive magnetostrictive material, and a scrim plated with strain-sensitive magnetostrictive material;
- wherein a magnetic sensor is used to sense a change in magnetization of the adhesive, the change indicating a change in strain in the adhesive, the strain in the adhesive indicating load carrying capability between the adhesive and the structures.
