A method and product for creating a customizable fabric for specific end-use composites is provided. This method includes creating a three-dimensional matrix on woven fabrics, such as glass or carbon fiber fabrics via the addition of nanoparticles and a coupling agent; and, attaching a functional group compatible to specific resins dependent upon end use. The resulting product is a resin-free fabric with specific functional groups attached, ready to receive a particular polymer resin. Alternatively, the process may continue through to the addition of a polymer resin, resulting in a completed composite product.
