Selectively meltable adhesives for bonding of deicers
A method of making an adhesive for an ice protection assembly includes mixing ferrous nanoparticles into the adhesive. Removal of the adhesive for ice protection assembly inspection or repair includes heating the ferrous nanoparticles in the adhesive to soften the adhesive and allow for easy removal or repositioning of the ice protection assembly.
1. An ice protection assembly comprising:
an aircraft component having a surface;
an adhesive on the surface of the aircraft component, wherein the adhesive is loaded with nanoparticles, wherein the nanoparticles are ferrous particles; and
a heater 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 nanoparticles are electrically conductive nanowires.
4. The assembly of claim 1 , wherein the adhesive comprises a pressure sensitive adhesive.
5. The assembly of claim 4 , wherein the pressure sensitive adhesive is selected from the group consisting of include acrylates, silicones, nitriles, and styrenes.
6. The assembly of claim 3 , wherein the adhesive is a thermoplastic adhesive selected from the group consisting of ethylene vinyl acetates, polyolefins, polycarbonates, acrylonitrile butadiene styrenes, and polyurethane hot melt adhesives.
7. The assembly of claim 1 , wherein the nanoparticles are no more than 25% by volume of the adhesive.
8. The assembly of claim 1 , further comprising a primer on the surface of the aircraft component configured to increase adhesion of the adhesive on the surface.
