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: Systems and methods are provided for enhancement of vacuum bagging processes for a composite part. One system includes dispensers configured to dispense materials onto a forming tool for a composite part, and a controller. The controller is able to identify a location for placing the composite part on the tool, and to direct the dispensers to lay up a laminate of constituent material for the composite part at the location. The controller is also able to direct the dispensers to spray vacuum bag material atop the laminate to form a vacuum bag that covers the laminate.

Abstract: A method and system for inspecting a structure. The method may comprise sending a pulsed wave signal into the structure from a transmitter array. The method may detect a response signal in response to sending the pulsed wave signal into the structure at a group of receivers in a receiver array. The method may identify a group of time delays between sending the pulsed wave signal and may detect the response signal generated in response to the pulsed wave signal at the group of receivers. The method may identify a group of intensities for the response signal detected at the group of receivers. The method may determine a distance to a reflector within the structure using the group of time delays and the group of intensities.

Abstract: Systems are disclosed for curing composite parts within a container, wherein a pressurized environment may be created via a body of water. Disclosed systems may include the container, a heating system, and a mechanism for raising and/or lowering the container within the body of water. The container may include one or more rigid walls, one or more non-rigid walls, and/or one or more port holes extending through one or more of the rigid walls and/or non-rigid walls. Methods of curing composite parts using such systems are also disclosed. Methods may include providing a container having a cavity configured to receive a composite part, thermally coupling a heating system to the container, inserting the composite part into the cavity, submerging the container under a depth of external liquid, flowing a volume of fluid into the cavity, heating the volume of fluid, thereby curing the composite part.

Abstract: Systems and methods are provided for enhanced vacuum bags. One embodiment is a method that includes placing a laminate comprising uncured fiber reinforced polymer onto a mandrel, laying up a vacuum bag, which includes integral ultrasonic transducers within a gas-impermeable layer, atop the laminate, and sealing the vacuum bag to the mandrel. The method also includes drawing a vacuum on the laminate via the vacuum bag, removing gas between the integral ultrasonic transducers and the laminate, and interrogating the laminate with the integral ultrasonic transducers.

Abstract: A method of decoupling an adhesive system from a contact surface of an object is disclosed. The adhesive system has a full adhesive strength in a de-energized state. The adhesive system comprises a backing, carbon nanotubes, each having a first end region, coupled to the backing, and a second end region, opposite the first end region, and charged nanoparticles, each coupled to the second end region of at least one of the carbon nanotubes. The method comprises steps of electrically charging the backing and disengaging the adhesive system from the contact surface. Electrically charging the backing creates an electrical repulsion force between the backing and the charged nanoparticles, so that the full adhesive strength of the adhesive system is decreased to a reduced adhesive strength. Disengaging the adhesive system from the contact surface comprises applying a disengagement force to the adhesive system sufficient to overcome the reduced adhesive strength.

Abstract: A dimmable window apparatus is provided. The dimmable window apparatus includes a window including a first linear polarizing film and a second linear polarizing film, the first linear polarizing film and the second linear polarizing film having respectively a first axis of polarization and a second axis of polarization, the second axis of polarization being electronically-controllable. The apparatus further includes a processor coupled to the second linear polarizing film, and configured to control the second axis of polarization to thereby control the opacity of the window that is defined by the first axis of polarization and the second axis of polarization relative to one another.
