1. A process for forming a resin-fiber composite, comprising the steps of providing an aqueous solution comprising an ionizable moiety, the ionizable moiety selected from the group consisting of polyamic acid, phenyl phosphinic acid, polyisobutylene-alt-maleic acid, polyphosphazene, polymetallophosphazene, polyborazine, phosphonicacidmethylene iminodiacetic acid, polyferrocene, polymetallocene, polysulfone, polyquinoxaline, polyether ether ketone (PEEK), and any combination thereof;disposing an electrically conductive fibrous substrate within the aqueous solution, wherein the fibrous substrate serves as an anode;contacting a second conductive body with the aqueous solution, wherein the second conductive body serves as a cathode;applying an electric potential between the anode and the cathode;ionizing the ionizable moiety in the aqueous solution;covalently bonding the ionizable moiety to the fibrous substrate to form a composite fiber;maintaining the electrodeposition conditions until at least one additional layer of the ionizable moiety is deposited on top of the resin matrix; andimpregnating the composite fiber with polyamic acid. 2. The process of claim 1, wherein the electrically conductive fibrous substrate is carbon fiber. 3. The process of claim 1, further comprising the step of curing the deposited resin matrix. 4. The process of claim 1, wherein the aqueous solution contains an organic solvent. 5. A composite structure formed according to the process of claim 1, wherein the composite substrate comprises a fibrous substrate having polyphosphinohydrazide covalently bonded to a surface thereof. 6. The composite structure of claim 5, wherein the structure takes the form of a composite fastener. 7. The composite structure of claim 6, wherein the composite fastener is a bolt or composite rivet. 8. The composite structure of claim 5, wherein the composite is a structural component of an aircraft. 9. The process of claim 1, wherein the ionizable moiety is polyphosphinohydrazide, and wherein the resulting resin-fiber composite has fire retardant properties. 10. A process for forming a resin-fiber composite, comprising the steps of providing an aqueous solution comprising an ionizable moiety, the ionizable moiety selected from the group consisting of polyamic acid, polypyrrole, polyaniline, phenyl phosphinic acid, polyisobutylene-alt-maleic acid, polysiloxane, polyphosphazene, polymetallophosphazene, polyborazine, phosphonicacidmethylene iminodiacetic acid, polyphosphinohydrazide, polyferrocene, polymetallocene, polysulfone, polyquinoxaline, polyether ether ketone (PEEK), and any combination thereof;disposing an electrically conductive fibrous substrate within the aqueous solution, wherein the fibrous substrate serves as an anode;contacting a second conductive body with the aqueous solution, wherein the second conductive body serves as a cathode; and,applying an electric potential between the anode and the cathode, thereby causing the ionizable moieties to ionize and to be electrodeposited as a resin matrix upon the fiber surfaces of the fibrous substrate,covalently bonding the ionizable moiety to the fibrous substrate to form a composite fiber;maintaining the electrodeposition conditions until at least one additional layer of the ionizable moieties are deposited on top of a nanomolecular layer. 11. The process of claim 10 wherein the ionizable moiety is a polysiloxane(amide-ureide) of the formula Ia whereinfor each repeat unit of the polymer, R1 and R2 are independently selected from the group consisting of C1 to C10 alkyls, aryls, and polyaryls; for each repeat unit of the polymer, R3 and R4 are independently selected from the group consisting of hydrogen, C1 to C6 alkyls, aryls, C3 to C6 cycloaliphatics, and C3 to C6 heterocycles; for each repeat unit of the polymer, A1 and A2 are independently selected from the group consisting of hydrogen, C1 to C6 alkyls, aryls, polyaryls, C3 to C6 cycloaliphatics, and C3 to C6 heterocycles; for each repeat unit of the polymer, x is a number from 1 to 1000; for each repeat unit of the polymer, Y is selected from a dicarboxyl residue and a non-linear diisocyanate residue, and wherein the polymer comprises at least one repeat unit where Y is a dicarboxyl residue and at least one repeat unit where Y is a nonlinear diisocyanate residue. 12. The process of claim 10, wherein the electrically conductive fibrous substrate is a carbon fiber. 13. The process of claim 10, wherein electrodeposition conditions are maintained until no substantial void space remains within the fibrous substrate. 14. The process of claim 10, wherein the electrodeposition conditions are discontinued while void spaces remain within the fibrous substrate; and, further comprising the step of subsequently resin impregnating the fibrous substrate by a resin infusion technique. 15. The process of claim 10, further comprising the step of curing the deposited resin matrix. 16. The process of claim 10, wherein the aqueous solution contains an organic solvent. 17. A composite structure formed according to the process of claim 10 wherein the composite structure comprises a fibrous substrate having an ionizable moiety covalently bonded to a surface thereof. 18. The composite structure of claim 17, wherein the structure takes the form of a composite fastener. 19. The composite structure of claim 18, wherein the composite fastener is a bolt or composite rivet. 20. The composite structure of claim 17, wherein the composite is a structural component of an aircraft. 21. The process of claim 10, wherein the ionizable moiety is polyphosphinohydrazide, and wherein the resulting resin-fiber composite has fire retardant properties.
