LOCKING HOLE PLUG FOR SEALING HOLES IN COMPOSITE STRUCTURES
A hole plug that can be used during rework or repair of a composite fiber assembly includes various features that allow placement of a vacuum force to the surface being reworked or repaired. In some implementations, the hole plug can include a plurality of nubs positioned around a shank. The nubs can secure the hole plug to the composite fiber assembly until a cure of an adhesive. The hole plug can further include a plurality of longitudinally oriented grooves extending along the shank and positioned between the plurality of nubs, and can include a notch positioned circumferentially around the shank. The grooves and notch can be used as adhesive carriers that assist with dispersal of a sufficient volume of the adhesive onto other portions of the shank and the composite fiber assembly during insertion of the hole plug into a hole in the composite fiber assembly.
REINFORCING ARTICLE
A reinforcing article includes a porous substrate layer separating a plurality of parallel first continuous fiber elements spaced apart from each other and extending along a first direction from a plurality of parallel second continuous fiber elements spaced apart from each other and extending along a different direction. Each first and second continuous fiber elements include a plurality of parallel and co-extending continuous fibers embedded in a thermoplastic resin.
Integral ceramic matrix composite fastener with non-polymer rigidization
A method of forming an integral fastener for a ceramic matrix composite component comprises the steps of forming a fiber preform with an opening, forming a fiber fastener, inserting the fiber fastener into the opening, and infiltrating a matrix material into the fiber preform and fiber fastener to form a ceramic matrix composite component with an integral fastener. A gas turbine engine is also disclosed.
Preformed Foundation Support For a Marine Vessel Gyro-Stabilization System
A preformed foundation support for a vessel gyro-stabilization system, comprises at least three of a first side support, a second side support, a third side support, and a fourth side support. The side supports define an opening for accommodating at least a portion of a vessel gyro-stabilization system, and the side supports comprise a cuttable portion for custom fitting the preformed foundation support in a vessel. The preformed foundation support structure is installed in the vessel by cutting the cuttable portion of the preformed foundation support for custom fitting the preformed foundation support to the structure support of the vessel. The preformed foundation support structure can be manufactured as a molded fiberglass structure.
Container for storing liquids and manufacturing method thereof
A container for storing liquids includes an inner layer including a storage space for storing liquids; an outer layer; and multiple spacers fastened between the inner layer and the outer layer to form multiple compartments. The spacer includes a first surface and a second surface. The first surface is secured to an adhesive layer of the inner layer. The first surface has many cavities. The second surface is secured to the outer layer and having projections complimentarily secured to the cavities. A manufacturing method of the container is also provided. Therefore, it can solve the problem permeation and adhesive failure caused by leaking. It can generate an early alarm by detecting any leaking or permeation of the container.
Handle Grip and Process for Making Same
A handle grip and process for making such handle grip. The handle grip comprises a cording arranged in a spaced knotted configuration around and along a handle. The spaced knotted cording is first entirely covered with a permeable woven layer. The permeable woven layer is covered with a hardener that permeates the woven layer and secures the woven layer and cording to the handle in water-tight fashion.

Co-molded metallic fan case containment ring
A method of fabricating a fan case for a gas turbine engine defines a metallic ring including an outer surface and an inner surface. A first composite material is assembled about the outer surface of the metallic ring. A second composite material is assembled about the first composite material. The first composite material and the second material are cured about the metallic ring within a tool to form a first subassembly. The first subassembly is removed from the tool. A fan case assembly for a gas turbine engine and a gas turbine engine are also disclosed.

LOAD ENERGY-ABSORBER
A fiber-reinforced resin load energy-absorber has: a multi-layer woven fabric or laminated woven fabric as a reinforcement base material; a resin as a matrix; slits; binding threads; and reinforcing members. The reinforcement base material has corners formed by bending said reinforcement base material. Slits are provided at least in the portions of the reinforcement base material that form the corners. The binding threads bind each of the woven fabric layers in the multi-layer woven fabric or laminated woven fabric. The binding threads are configured so as to bind each of the woven fabric layers when the multi-layer woven fabric or laminated woven fabric is divided in the thickness direction into at least two woven fabric layers. The reinforcing members are held inside the slits.
