Abstract

A multilayered article is disclosed, the multilayered article including a thermosetting polymer material having at least one surface, a thermoplastic polymer layer deposited on the at least one surface of the thermosetting polymer material, a cold sprayed metal layer present on at least a portion of a surface of the thermoplastic polymer layer, at least one additional layer, the at least one additional layer sandwiching at least a portion of the cold sprayed metal layer between the additional layer and the thermoplastic polymer layer, where the thermoplastic polymer layer has a crystallinity of about 5% to about 60%. A method of providing a composite laminate structure is also disclosed.

First claim

a cold sprayed metal layer present on at least a portion of a surface of the thermoplastic polymer layer;
at least one additional layer, the at least one additional layer sandwiching at least a portion of the cold sprayed metal layer between the additional layer and the thermoplastic polymer layer; and wherein:
the thermoplastic polymer layer has a crystallinity of about 5% to 25%; and
the thermoplastic polymer layer adheres to the surface of the thermosetting polymer material due to curing of the thermosetting polymer material after deposition of the thermoplastic polymer layer.

2. The multilayered article of claim 1 , wherein the thermosetting polymer material comprises an epoxy resin.

3. The multilayered article of claim 1 , wherein the thermosetting polymer material comprises multiple layers.

4. The multilayered article of claim 1 , wherein the thermosetting polymer material further comprises one or more fillers or reinforcement materials comprising carbon, carbon nanotubes, graphite, carbon fibers, graphite fibers, fiberglass, glass fibers, metals, metal alloys, metalized fibers or metal coated glass fibers.

5. The multilayered article of claim 1 , wherein the thermoplastic polymer layer comprises a carbon fiber or glass fiber reinforced poly-ether-ether-ketone (PEEK) or poly-ether-ketone-ketone (PEKK).

6. The multilayered article of claim 1 , wherein the cold sprayed metal layer is selected from silver, gold, aluminum, cobalt, chromium, copper, iron, nickel, molybdenum, palladium, platinum, rhodium, ruthenium, tin, titanium, tungsten, zinc, zirconium, or alloys thereof.

7. The multilayered article of claim 1 , wherein the multilayered article is a component or part of an aerospace vehicle.

8. The multilayered article of claim 7 , wherein the component or part of an aerospace vehicle is an external surface thereof.

9. The multilayered article of claim 1 , further comprising:
a second thermoplastic polymer layer having a first surface and a second surface wherein the first surface is deposited on a second surface of the at least one surface of the thermosetting polymer material;
a second cold sprayed metal layer present on at least a portion of the second surface of the second thermoplastic polymer layer; and
wherein the second thermoplastic polymer layer has a crystallinity of about 5% to about 60%.

10. The multilayered article of claim 9 , wherein the second thermoplastic polymer layer comprises a carbon fiber or glass fiber reinforced poly-ether-ether-ketone (PEEK) or poly-ether-ketone-ketone (PEKK).

providing a multilaminate thermosetting polymer structure prior to the multilaminate thermosetting polymer structure being in a fully cured state;
depositing a thermoplastic polymer layer having a crystallinity of about 5% to 25% onto a first surface of the multilaminate thermosetting polymer structure;
forming a cold sprayed metal layer by introducing particles of a metal powder to a gas stream;
directing the gas stream toward the thermoplastic polymer layer, wherein the gas stream has a temperature and pressure adjusted to prevent thermal softening or ablation of the surface of the thermoplastic polymer layer;
forming the cold sprayed metal layer on at least a portion of the thermoplastic polymer layer;
applying an additional layer, the additional layer sandwiching at least a portion of the cold sprayed metal layer between the additional layer and the thermoplastic polymer layer; and
curing the multilaminate thermosetting polymer structure along with the thermoplastic polymer layer after depositing the thermoplastic polymer layer.
