In one embodiment, the present invention involves a method that comprises the combination of two process technologies; a thin film solution casting process (tape casting, solvent casting) and an electrospinning process, in order to produce hybrid materials of thin polymer films with single, laminated, completely and/or partially embedded electrospun nanofibers to obtain products with unique functional properties. In another embodiment of the present invention, fibers and/or nanofibers of a chosen material are spun directly on to substrates of polymer solutions and/or monomers solutions, were such solutions are located on a carrier belt that is electrically and/or ionically conductive.

摘要： The invention relates to a novel method for electrospinning fibers wherein the fiber-spinning solution is infused with gas bubbles which travel through the electrospinning fluid, causing the bubbles to be coated with electrospinning solution. The coated bubbles, in turn, in response to an applied electrical force, generate jets of the electrospinning fluid that travel away from the bubble surface. The invention further relates to the fibers formed by this bubble-jet process and to products made therefrom.

摘要： A nozzle for forming nanofibers by using a pressurized gas stream comprises a center tube, a first supply tube that is positioned concentrically around and apart from the center tube, a middle gas tube positioned concentrically around and apart from the first supply tube, and a second supply rube positioned concentrically around and apart from the middle gas tube. The center tube and first supply tube form a first annular column. The middle gas tube and the first supply tube form a second annular column. The middle gas tube and second supply tube form a third annular column. The tubes are positioned so that first and second gas jet spaces are created between the lower ends of the center tube and first supply tube, and the middle gas tube and second supply tube, respectively. A method for forming nanofibers from a single nozzle is also disclosed.

摘要： A fiber reinforced composite material comprising a resin matrix and primary reinforcement fibers and further comprising secondary, smaller diameter, reinforcement fibers at one or more ply interfaces, or portion thereof, provides improved interlaminar toughness, strength, and delamination resistance without substantial reduction of in-plane properties and without substantial increase in weight. In one embodiment, the small fibers are attached to one side of a conventional prepreg prior to lamination. The small fibers are flexible and are expected to conform to the shape and distribution of the primary reinforcing fibers at the interface.
