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 chemical vapor deposition method comprises flowing a carrier liquid through a reactor. A fluid comprising one or more reactants is introduced into the carrier liquid. The fluid is at a first temperature and first pressure and is sufficiently immiscible in the carrier liquid so as to form a plurality of microreactors suspended in the carrier liquid. Each of the microreactors comprise a discrete volume of the fluid and have a surface boundary defined by an interface of the fluid with the carrier liquid. The fluid is heated and optionally pressurized to a second temperature and second pressure at which a chemical vapor deposition reaction occurs within the microreactors to form a plurality of chemical vapor deposition products. The plurality of chemical vapor deposition products are separated from the carrier liquid. A system for carrying out the method of the present disclosure is also taught.

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: An adhesive system (100) for attachment to a contact surface (122) of an object (120) comprises a backing (110), carbon nanotubes (130), charged nanoparticles (150), and an electrical source (160). The carbon nanotubes (130) each have a first end region (132) and a second end region (134), opposite the first end region (132). Each of the charged nanoparticles (150) is coupled to the second end region (134) of at least one of the carbon nanotubes (130). The electrical source (160) is configured to selectively electrically charge the backing (110) to cause an electrical repulsion force between the backing (110) and the charged nanoparticles (150). The first end region (132) of each of the carbon nanotubes (130) is coupled to the backing (110). The second end region (134) of each of a number of the carbon nanotubes (130) is coupled to none of the charged nanoparticles (150).

Abstract: A method and apparatus for heating a part. The part is heated with the part at least partially surrounded by a surface of a tooling system, while a heatsink system is positioned relative to the part. A thermal conduction between the heatsink system and the part is changed during heating of the part.
