    Abstract: A method of forming a thinned prepreg sheet is disclosed. The method comprises providing a first precursor sheet comprising reinforcement fibers impregnated with a matrix resin in a first state. The method also comprises forming a second precursor sheet having a first thickness by cooling the first precursor sheet until the matrix resin is transformed from the first state to a second state. The method further comprises forming a crushed sheet comprising interstices having an average size by crushing the second precursor sheet, where the crushed sheet has a second thickness. The method also comprises forming the thinned prepreg sheet by heating the crushed sheet until the matrix resin is transformed from the second state to a third state. The thinned prepreg sheet has a third thickness less than the first thickness of the second precursor sheet.

    Abstract: Systems and methods are provided for stitching together sheets of interwoven carbon nanotubes. One embodiment is a method that includes providing multiple sheets of interwoven carbon nanotubes, arranging the sheets over a substrate such that interstices of the sheets overlap at a stitch region of the substrate and heating catalysts at the substrate above a threshold temperature to trigger growth of new carbon nanotubes. The method also includes adjusting alignment of an electrical field that defines a direction of growth of the new carbon nanotubes, thereby causing the new carbon nanotubes to grow through the interstices and then stitch the sheets together.

    Abstract: A system for use in producing a nanotube mesh structure is provided. The system includes a first nanotube collection apparatus including a first substrate configured to collect a plurality of nanotubes substantially aligned in a first orientation on an attachment surface thereof, and a second nanotube collection apparatus including a second substrate configured to collect a plurality of nanotubes substantially aligned in a second orientation on an attachment surface thereof. The first and second nanotube collection apparatuses are configured to combine the pluralities of nanotubes at an interface. The system also includes a first energy source configured to direct energy towards the interface between the pluralities of nanotubes, wherein the energy is configured to join the pluralities of nanotubes to form the nanotube mesh structure.

    Abstract: A system (100) for making a prepreg composite sheet (300) comprising contoured charges (308) comprises first means (102) for forming precursor outline regions (206) in a resin film layer (200). The system (100) also comprises second means (106) for impregnating a fiber reinforcement (220), comprising fibers (222), with the resin film layer (200), comprising the precursor outline regions (206), to form the prepreg composite sheet (300). The prepreg composite sheet (300), as so formed, comprises non-impregnated outline regions (310) that define the contoured charges (308). The non-impregnated outline regions (310) in the prepreg composite sheet (300) correspond to the precursor outline regions (206) in the resin film layer (200). The system (100) further comprises third means (104) for guiding the fiber reinforcement (220) and the resin film layer (200) to the second means (106). The resin film layer (200) comprises the precursor outline regions (206) formed by first means (102).
