Fiber based z-directional reinforced composites having enhanced inter-laminar strength, impact toughness, transmission properties (electrical and thermal conduction) and coefficient of thermal expansion are provided. The composites include at least two substrates separated by a reinforcement zone that includes a plurality of fibers disposed in a binder resin. At least some, and in one embodiment, a majority, of the fibers are oriented so as to be substantially perpendicular to the substrates. Multi-layered composites having more than two substrate layers can also be formed. Methods for forming such composites are also provided.

What is claimed is: 1. A composite, comprising:a plurality of substrates; anda reinforcement zone disposed between adjacent substrates of the plurality of substrates, the reinforcement zone having a binder resin and a plurality of fibers, a majority of which are oriented substantially perpendicular to the substrates, the substantially perpendicularly oriented fibers spanning adjacent substrate layers and being embedded in the adjacent substrate layers,wherein the reinforcement zone further comprises a plurality of fibers oriented at a non-orthogonal angle to the plurality of substrates and a plurality of branched fibers, each branched fiber extending from one of the plurality of fibers oriented substantially perpendicular to the substrates or from one of the plurality of fibers oriented at a non-orthogonal angle to the plurality of substrates.
