Abstract: Composite laminate parts are made using a gradient cured subset of fiber reinforced thermoset resin plies. A portion of the subset is cured to rigidity to thereby maintain the shape of a part layup, while other plies in the subset are actively cooled to prevent them from curing. Additional plies are laid up on the uncured plies of the subset to complete the layup. The completed layup is then fully cured.

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: A fabricated substrate has at least one plurality of posts. The plurality is fabricated such that the two posts are located at a predetermined distance from one another. The substrate is exposed to a fluid matrix containing functionalized carbon nanotubes. The functionalized carbon nanotubes preferentially adhere to the plurality of posts rather than the remainder of the substrate. A connection between posts of the at least one plurality of posts is induced by adhering one end of the functionalized nanotube to one post and a second end of the functionalized carbon nanotube to a second post.
