Abstract: A system and method for manufacturing composite parts has been developed which offers the ability to produce composite parts in an infusion resin process without the use of expensive preforms or tools. In addition, the methods of manufacturing composite parts described herein offer the ability to produce composite parts having complex structures without the need for complex tooling. The method of manufacturing and systems described herein typically include printing a part skeleton using an additive manufacturing process followed by infusing the part skeleton with resin and curing the resin infused part skeleton to form the composite part.

Abstract: A pressure vessel for storing hydrogen is described. The pressure vessel includes at least one chamber to store hydrogen atoms. The pressure vessel also includes a mycelium structure within the at least one chamber. The mycelium structure has a surface area of at least 800 m2/m3. At least some of the hydrogen atoms are attached to the mycelium structure at a pressure greater than ambient pressure. Methods of storing hydrogen and methods of constructing a hydrogen storage tank are also described.

Abstract: A blade-protecting sheath is configured to protect a cutting blade of an ultrasonic cutting system. The blade-protecting sheath includes a main body having a first end and an opposite second end, a blade-receiving channel formed through the first end, and a nut-retention chamber connected to the blade-receiving channel. The nut-retention chamber is defined by interior planar walls that are configured to receive and constrain a nut of the ultrasonic cutting system. A blade slot is connected to the nut-retention chamber. The cutting blade is configured to pass into the blade slot and be secured within a blade chamber.

Abstract: Methods, systems and apparatuses are disclosed for making and post-processing a 3-D printed object for laminate-forming tooling, and components made using post-processed 3-D printed laminate-forming tooling.

Abstract: Devices, systems and methods for compacting a charge of composite material across an edge are disclosed herein. The devices include a vacuum compaction device including a compaction force transfer structure, a sealing structure, and a vacuum distribution manifold. The compaction force transfer structure includes a first barrier structure, a second barrier structure, and a junction support that extends at least partially between the first barrier structure and the second barrier structure. The junction support is configured to maintain the first barrier structure and the second barrier structure at an angle with respect to one another and to permit limited angular motion of the first barrier structure and the second barrier structure relative to one another. The systems include composite structure fabrication systems that include the vacuum compaction device. The methods include methods of operating the vacuum compaction device.
