Abstract: A method of making an indexed prepreg composite sheet is disclosed. The method comprises forming discrete regions in a resin film layer. The discrete regions are arranged in an indexing pattern. The method also includes forming a precursor prepreg composite sheet by impregnating a fiber reinforcement with the resin film layer having a viscosity. The discrete regions of the resin film layer form non-impregnated regions of the precursor prepreg composite sheet. The method additionally includes replacing the non-impregnated regions of the precursor prepreg composite sheet with indexing openings.

Abstract: Composite materials having carbon reinforcement fibers impregnated with a matrix material are augmented with functionalized graphene nanoplatelets having amine groups formed on a surface of the graphene nanoplatelets and epoxide groups formed on at least one edge of the graphene nanoplatelets as a supplement to or a replacement for resin matrix material to increase strength of the composite materials. Related methods of increasing strength of composite materials include mixing the functionalized graphene nanoplatelets into the matrix material prior to impregnating the carbon reinforcement fibers, depositing the functionalized graphene nanoplatelets onto the matrix material to form an interlayer, and depositing the functionalized graphene nanoplatelets onto a bed of carbon reinforcement fibers with no resin matrix material. The composite materials and related methods for increasing strength of composite materials may include graphene nanoplatelets having holes formed through the graphene nanoplatelets.

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.

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: Systems and methods are provided for ultrasonic image generation. One embodiment is a method that includes capturing a first ultrasound image that represents a first volume within a part, and capturing a second ultrasound image that represents a second volume that partially overlaps the first volume. The method also includes identifying a first constellation comprising at least three inconsistencies in the part that are depicted in the first ultrasound image, identifying a second constellation, comprising a reoriented version of the first constellation, in the second ultrasound image, and generating an aggregate image that combines the first ultrasound image with the second ultrasound image.
