Abstract

The present invention is a new type of hybrid high-strength carbon-fiber/epoxy composites reinforced with ultrathin toughening and self-healing core-shell fibers at interfaces by means of wetted lay-up, followed by vacuum-assisted resin transfer molding (VARTM) technique. The core-shell fibers loaded with liquid healing agent (a liquid monomer at room temperature) are produced by co- electrospinning, in which a plastic polymer solution (dissolved in an organic solvent) is used as the exterior jet and the monomer solution (dissolved in the same organic solvent) is used as the interior jet. Also described is a fiber manufacturing device utilizing a novel dual-wire emulsion-electrospinning method capable of producing ultrathin continuous core-shell and hollow fibers in commercial volumes.
