Disclosed herein are a repair apparatus, system, and method for structurally reinforcing an abnormal composite structural member. The repair is suited for reinforcing a cured composite structure that defines a strength tolerance and has an abnormality that reduces the structural strength relative to the strength tolerance of the cured composite. The structural reinforcement repairs the abnormality in the cured composite and provides the repair strength so that the repaired composite has a structural strength that meets or exceeds the strength tolerance. The structural reinforcement has a composite patch that is coupled to the cured composite over the abnormality and is covered by pressure-sensitive tape.

An aircraft includes a flight deck including a flight deck door configured to be moved between an open position and a closed position, a first monument, second monument, and a secondary barrier door moveably secured between the first monument and the second monument. The secondary barrier door is configured to fold into a stowed position in which a path to the flight deck is open, and unfold into a deployed position in which the path to the flight deck is closed.

Composite laminates fabricated from one or more respective laminae of composite material (e.g., fiber-reinforced polymers) may be pre-formed and fully cured, yet configured to be selectively conformable to a desired radius of curvature. To repair a damaged composite structure, a plurality of such composite laminates may be bonded together to form a repair part that may be bolted to or otherwise secured to the damaged composite structure, thereby repairing the structure using repair parts that may match the parent material of the damaged composite structure. Methods of forming said repair parts from a plurality of such composite laminates may provide advantages in costs and lead time, over conventional techniques. Kits may include a plurality of such pre-formed and cured composite laminates that may be stacked and combined together in a plurality of different arrangements to create a customizable repair part for a given damaged composite structure.

Disclosed herein are a repair apparatus, system, and method for a composite sandwich structure. The repair is suited for reinforcing a sandwich panel having a first sheet and a second sheet opposite the first sheet. A core is interposed between and coupled to the first sheet and the second sheet. The repair uses a potting compound packed into an abnormality of the core and located on the outer surface of the first sheet. A patch is coupled to the outer surface of the first sheet over the abnormality of the core and cured. The cured potting compound is interposed between and bonded to the patch and the abnormality of the core and bonded to the patch and the outer surface of the first sheet to form a structural reinforcement.

A rework part for a composite structure is described. The rework part comprises an upper composite layer comprising an upper perimeter that extends beyond a damaged area of the composite structure, and a bottom composite layer between the composite structure and the upper composite layer, the bottom composite layer comprising a bottom perimeter that extends beyond the upper perimeter of the upper composite layer. The rework part further comprises a bottom adhesive layer adhering the bottom composite layer to the composite structure, and a rework part adhesive layer bonding the upper composite layer to either the bottom composite layer or to an intermediate composite layer.

The present invention is a manual non-mechanized device that consists of a base and a guide. This invention is a device that provides an expeditious method to invert or turn inside-out and to reform or turn glove appendages back to the proper side, that has numerous openings, one of which accepts a guide. The guide is defined as an asymmetrical cylinder having two (2) opposing ends. One end has a concave configuration and above and adjacent to the other end are a couple of grooves that circumscribe the guide with a couple of flexible elements fitted therein. The latter end is fitted into one of the openings in the base, to be securely mounted therein without using threaded means. The present invention facilitates efficient cleaning and/or rapid drying of the lining and quick reformation to the proper side with a proper fit. The main objective of the present invention is to promote healthy, morbidity free hands in the workplace and at home.

Methods, apparatuses and systems are disclosed for making and applying composite material rework parts to rework composite substrates by partially forming a composite material rework part before staging the rework part onto the composite substrate. An approximate geometry is imparted to the partially formed rework part, with the final composite material rework part geometry imparted by the composite substrates requiring rework, as the rework part is finally shaped and cured in situ on the composite substrate.

Composite material rework parts and methods of making composite rework parts

Apparatus for stabilizing a test specimen in a compression/tension testing machine. The apparatus supports the test piece along its lengthwise edge or edges to prevent unwanted Euler buckling, however in a manner so as not to prevent sublaminate buckling. In one embodiment the apparatus supports the test piece along both of its lengthwise edges while engaged between the grips of the test machine. In a second embodiment, the apparatus supports the test piece along only one of its lengthwise edges. In a third embodiment, the apparatus includes grip plates which are mounted to the test machine and which engage a portion of the test specimen while the remainder of the specimen is supported along its lengthwise edges by stabilizer plates.
