A binder is applied to particles (602) which are then combined with fibers (600) to bind the particles to the fibers (600). The particles (602) have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers (600) have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles (602) that are adhered to the fibers (600) may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers (600) by hydrogen bonds. Fibers (600) containing particles (602) bound by this method are easily densified.
