ABSTRACT:
Disclosed is a method of attaching a substantially uniform distribution of particulates to individual exposed surfaces of a matrix of fibrous material. The method includes the following steps: 1) electrically charging a matrix of fibrous material having individual exposed surfaces to create a substantially uniform distribution of charged sites at the exposed surfaces; 2) applying particulates to the charged matrix of fibrous material so that at least some particulates adhere at the charged sites; and 3) attaching particulates adhering to the fibrous material at charged sites by substantially non-transient bonding. Also disclosed is a fibrous composite structure composed of a matrix of fibrous material having individual exposed surfaces; and a relatively uniform distribution of particulate material attached to individual exposed surfaces of the fibrous material by substantially non-transient bonding.
