Z-CNT filled meltable adhesives for bonding of deicers
A method of making an adhesive for an ice protection assembly includes transferring Z-CNTs from a substrate carrier into the adhesive. De-bonding of the adhesive for ice protection assembly inspection or repair or repositioning at initial installation includes heating the Z-CNTs in the adhesive to soften the adhesive and allow for easy removal.
1. An ice protection assembly comprising:
an aircraft component having a surface;
a primer on the surface of the aircraft component configured to increase adhesion of the adhesive on the surface
an adhesive on the primer on the surface of the aircraft component, wherein the adhesive is loaded with vertically aligned carbon nanotubes (Z-CNTs); and
a de-icer attached to the aircraft component by the adhesive.
2. The assembly of claim 1 , wherein the aircraft component is selected from the group consisting of an airfoils, nacelles, nosecones, engine cowls, and leading edges.
3. The assembly of claim 1 , wherein the adhesive comprises a thermoplastic adhesive.
4. The assembly of claim 3 , wherein the thermoplastic adhesive is pressure sensitive adhesive, selected from the group consisting of include acrylates, silicones, nitriles, and styrenes.
5. The assembly of claim 3 , wherein the thermoplastic adhesive is hot melt adhesive.
6. The assembly of claim 1 , wherein the Z-CNTs are no more than 50% by weight of the adhesive.
7. The assembly of claim 1 , wherein the de-icer is pneumatic de-icer or an electrothermal de-icer.
8. The assembly of claim 1 , wherein the Z-CNTs are aligned at a 90 degree angle relative to the adhesive surface.
9. The assembly of claim 1 , wherein the Z-CNTs are parallel to the adhesive surface.
