What is claimed is: 1. A composite article essentially free of microvoids comprising: (a) a first permeable substrate layer; and (b) a first cured polymer matrix layer in contact with said first permeable substrate layer, comprising: (i) a cured resin; and (ii) a reinforcing material in contact wit
What is claimed is: 1. A composite article essentially free of microvoids comprising: (a) a first permeable substrate layer; and (b) a first cured polymer matrix layer in contact with said first permeable substrate layer, comprising: (i) a cured resin; and (ii) a reinforcing material in contact with said cured resin, wherein uncured resin impregnates said first substrate layer using a resin transfer molding process whereby the first contact of the uncured resin and permeable substrate layer occurs under pressure sufficient to create a composite article essentially free of microvoids, the pressure created by applying gas or flowable liquid pressure to a precursor of said article comprising said substrate, an uncured precursor of said cured resin and said reinforcing material. 2. The composite article according to claim 1, wherein said cured resin impregnates said first permeable substrate layer to a depth of from about 1% to about 100% of a cross-section of a porous region of said substrate. 3. The composite article according to claim 1, wherein said gas or flowable liquid pressure is from about 10 psi to about 300 psi. 4. The composite material according to claim 1, wherein said substrate comprises a patterned surface. 5. The composite article according to claim 1, wherein said first amount of resin is a preselected amount. 6. The composite article according to claim 1, further comprising a second substrate in contact with said polymer matrix layer. 7. The composite article according to claim 6, wherein a second amount of said cured resin impregnates said second substrate. 8. The composite article according to claim 1, wherein said first substrate layer comprises a first sub-component and a second sub-component in a layered arrangement in which a third amount of said resin is in contact with said first sub-component and said second sub-component. 9. The composite article according to claim 1, wherein said first substrate and said second substrate are the same material or different materials. 10. The composite article according to claim 8, wherein said first sub-component and said second sub-component are the same material or different materials. 11. The composite article according to claim 1, wherein said reinforcing material is a fiber reinforcement that is a member selected from glass-based fiber, mineral-based fiber, carbon-based fiber, aramid-based fiber, natural fiber, metal-based fiber, basalt-based fiber, synthetic organic fiber. 12. The composite article according to claim 1, wherein said substrate layer is a consolidated material that is a member selected from wood products, wood composite products, wood-plastic products, plastic-lumber, wood thermoplastic extruded material, structural composite lumber and engineered wood composites. 13. The composite article according to claim 12, wherein said consolidated material is a member selected from wood-plastic composites, oriented strand board, plywood, laminated veneer lumber, parallel strand lumber. 14. The composite article according to claim 11, wherein said fiber is a member selected from a preform, a woven fabric, a non-woven fabric, stitched fabric, a braid, a roving, a tow, a chopped strand mat, a continuous strand mat, a veil and combinations thereof. 15. The composite article according to claim 1, wherein said cured polymer matrix layer comprises a member selected from a thermoset polymer, thermoplastic polymers and combinations thereof. 16. The composite article according to claim 1, wherein said cured polymer matrix layer comprises a member selected from epoxy resin, urethane resin, polyester resin, phenolic resin, polyvinyl chloride resin, melamine resin, isocyanate resin, resorcinol resin, polyethylene resin, polypropylene resin, and nylon resin and combinations thereof. 17. The composite article according to claim 6, wherein said polymer matrix layer forms a graded interphase between said first substrate and said second substrate. 18. The composite article according to claim 1, wherein said polymer matrix layer has a polymer matrix layer structural performance and said first substrate has a substrate structural performance, and said composite article has a composite article structural performance that is greater than the sum of said substrate structural performance and said polymer matrix layer structural performance. 19. The composite article according to claim 1, wherein a member selected from said first substrate, said reinforcing material, said first polymer matrix layer and combinations thereof further comprise a member selected from a preservative, a fire retardant material and combinations thereof.
