3M is on the Leading Edge of Innovation
Adhesive bonding enables a more lightweight structure because it allows you to use more lightweight composite, as opposed to the metallic materials that were used in previous designs. Structural adhesive films are employed anywhere you are trying to bond metal to composite. This offers good erosion performance while minimizing weight.
