Abstract:
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; and impregnating the composite fiber with polyamic acid.
