Composites, products made from composites and method of producing same are provided. The present invention includes an injection moldable product made from a composite material at least composed of balanced mixture of thermoplastics and fibrous components. The injection moldable product is formed into a body that has a wedge-shape, a shim-shape or the like wherein the body includes one or more cored regions extending though at least a portion thereof.

The invention is claimed as follows: 1. A composite shim comprising: a single part construction including a fiber-reinforced base material, the fiber-reinforced base material including a fibrous component and a thermoplastic component wherein the base material is formed into a shim-shaped body that has at least two rows of cored regions including one or more cored regions not exceeding three in number extending in a widthwise direction in each row along a first side of the shim-shaped body and through a portion of the shim-shaped body, wherein at least one of the rows includes three cored regions, wherein the rows of cored regions are positioned along the shim up to about two thirds of a length of the first side, wherein the shim-shaped body includes a second side opposite the first side, wherein the first side and second side converge to a tapered edge along a converging distance between the first and second sides, wherein the cored regions extend a distance between the first and second sides that is less than the converging distance, wherein the cored regions are structured and positioned so as to enable the composite shim to be secured while minimizing an amount of force exerted to the shim, thereby halting propagation of splitting caused by securing the composite shim through piercing at least one of the cored regions of the shim, and wherein the second side has a smooth surface that extends along an entire length of the second side. 2. The composite shim of claim 1, wherein the thermoplastic component is selected from the group consisting of polyethylene, polyesters, polystyrene, polycarbonate, polyvinylchloride, poly (methyl methacrylate), nylon, copolymers thereof and mixtures thereof. 3. The composite shim of claim 1, wherein the fibrous component is selected from the group consisting of synthetic fiber, carbon fiber, a cellulosic material, natural fiber, wood flour, birch wood flour, maple wood flour, spruce wood flour, pine wood flour, fir wood flour, rice hull, peanut shells, recyclable wood waste, recyclable paper, flax sheeve and combinations thereof. 4. The composite shim of claim 1, wherein the thermoplastic component ranges from about 30% to about 70% by weight of the composite shim and the fibrous component ranges from about 30% to about 70% by weight of the composite shim. 5. The composite shim of claim 1, wherein the base material comprises an additional component selected from the group consisting of a binder, a coloring agent, a scent agent, an ultraviolet light stabilizer, a filler, a natural filler, a heat stabilizer, an antioxidant, a foaming agent, a fungicide and combinations thereof. 6. The composite shim of claim 1, wherein the composite shim is non-weight bearing in size. 7. The composite shim of claim 1, wherein two or more of the rows include three cored regions. 8. The composite shim of claim 1, wherein the first and second sides converge from a third side that includes a recess. 9. The composite shim of claim 1, wherein the first side has a smooth surface that extends along an entire length thereof. 10. The composite shim of claim 1, wherein at least one of the rows of cored regions includes two cored regions and optionally includes a third cored region. 11. The composite shim of claim 1, wherein the length of the first side and the second side does not exceed about twelve inches, the converging distance does not exceed about 5/16 inches, and the width does not exceed about 1.5 inches. 12. The composite shim of claim 1, wherein the cored regions are tapered. 13. The composite shim of claim 1, wherein the cored regions extend approximately 0.06 inches between the first and second sides. 14. The composite shim of claim 1, wherein each of the cored regions are tapered at an angle of about eight degrees. 15. The composite shim of claim 1, wherein the cored regions are spaced apart from one another along the length of the first side by approximately 0.456 inches. 16. The composite shim of claim 1, wherein each cored region is cylindrical and has a diameter of approximately 0.32 inches. 17. The composite shim of claim 1, wherein the length of the first side and the second side does not exceed about eight inches, the converging distance does not exceed about 0.28 inches, and the width does not exceed about 1.5 inches.
