Fabrics with high thermal conductivity coatings
View Patent ↗The present invention facilitates the thermal conductivity of fabrics by surface coating of the fabrics with high thermal conductivity materials 6 . The fabrics may be surface coated when they are individual fibers or strands 4 , bundles of strands, formed fabric or combinations therefore. A particular type of fibrous matrix used with the present invention is glass. Some fabrics may be a combination of more than one type of material, or may have different materials in alternating layers. HTC coatings of the present invention include diamond like coatings (DLC) and metal oxides, nitrides, carbides and mixed stoichiometric and non-stoichiometric combinations that can be applied to the host matrix.
1. A fabric comprising:
a fibrous matrix woven into said fabric, forming a woven fabric layer,
a coating disposed on said fibrous matrix and having an average thickness of 50-100 nm on said fibrous matrix;
wherein said coating comprises at least one of a diamond like coating, a metal oxide, a metal nitride, and a metal carbide;
wherein said coating has mixed stoichiometric and non-stoichiometric combinations;
wherein said fabric has thermal conductivity of 50-500 W/mk; and
wherein said coating is within said woven fabric layer.
2. The fabric of claim 1 , wherein said fibrous matrix is glass fibers.
3. The fabric of claim 1 , wherein said fabric is further formed into an insulating tape.
4. The fabric of claim 1 , wherein said fibrous matrix is at least one of poly-imides, poly-amides, poly-ethylene terephthalate, polymeric microfibers, propylene polymers, and olefin polymers.
5. The fabric of claim 1 , wherein said coating is disposed on said fibrous matrix by at least one of chemical vapour deposition and physical vapour deposition.
6. The fabric of claim 1 , wherein a resin is impregnated in said fabric.
