COMPOSITE MATERIALS
First Claim
1. A composite material comprising:
- a fiber-containing layer comprising at least one of natural and synthetic fibers, said fiber-containing layer having at least one surface; and
a filler-containing layer coupled to the fiber-containing layer substantially continuously across the at least one surface of the fiber-containing layer, said filler-layer comprises fillers having particle size of from about 0.01 to about 50 microns, in an amount of from about 50% to about 90% by weight;
wherein the filler-containing layer comprises at least one binding agent present as a continuous phase in the layer in an amount of from about 10% to about 50% by weight;

Abstract
Composite materials having at least one of the following desirable properties is described. Such properties include: rigidity, printability, water-proofness, pliability, recyclable, thermochromic, antimicrobial, electrically conductive, compostable or biodegradability. The composite includes a filler-containing layer and a fiber-containing layer substantially coupled together continuously across the at least one surface of the layers. These composites maybe useful in various markets including, but not limited to, construction, packaging, shipping, consumer products and medical packaging. The inventive composites provide, advantages such as reduction of environmental footprint, improved mechanical properties, usefulness/cost ratio, reduction in material costs compared to prior art, and cosmetic performance are embodied in the present invention.
