Abstract:
1. The self-healing and adaptive shaped articles are in the form of fiber reinforced composites comprising structural fibers with diameters ranging from 1 nanometer to 1 millimeter, said structural fibers coated with piezoelectric materials with thickness ranging from 1 nanometer to 1 millimeter to form a coated structural fiber, and applied upon said coated piezoelectric material, solid electrolyte materials with thickness ranging from 1 nanometer to 1 millimeter, wherein the solid electrolyte materials comprise at least one solid electrolyte and at least one dissolved metal salt, the coated structural fibers are embedded in a structural matrix, wherein gradient stress distributions indicate development of critical areas with elevated stress levels induce, by the piezoelectric effect, gradient electric potentials which transport metal towards and deposit it at said critical areas by electrolytic processes within the solid electrolyte, rendering self-healing and adaptive effects and; wherein said piezoelectric materials comprise at least one of lead zirconate titanate (Pb[Zr wherein said solid electrolytes comprise at least one of poly(vinylidine fluoride-co-hexafluoropropylene), poly(vinylidine fluoride), polypyrrole, poly(ethylene oxide), poly(ethylene oxide methacrylate)-b-poly(lauryl methacrylate), poly(propylene oxide), polyvinyl butyral, polyurethane, polystyrene sulfonate, poly(epichlorohydrin ethylene oxide), hydroxyethyl cellulose grafted with poly(ethylene oxide)diisocyanate, carboxymethylcellulose grafted with poly(ethylene oxide)diisocyanate, polypyrrole/polysulfide blends, polypyrrole/polyetherimide blends, polyaniline/polyaniline-sulfuric acid blends, perfluorinated polymers, sulfonated polyetheretherketone, poly(acrylonitrile), poly(acrylonitrile-co-methylmethacrylate), and polyethylene glycol and; wherein said dissolved metal salts comprise at least one of copper(II) trifluoromethane sulfonate, AgNO
