Composite liners (such as acoustic panels, fan track liners, and/or ice impact panels or boxes for turbofan engines) and techniques for forming composite liners. In some examples, the composite liner includes at least one region comprising a reinforcement architecture comprising a matrix material, a plurality of relatively tough polymer-based reinforcement elements, and a plurality of second reinforcement elements. The plurality of relatively tough polymer-based reinforcement elements and the plurality of second reinforcement elements are embedded in the matrix material.

A method of making a vacuum insulated refrigerator structure includes positioning a core of overlapping stacked sheets of fiberglass mat in an envelope of impermeable barrier material. The core is pressed into a predefined three dimensional shape by pressing first and second mold parts together. The core is evacuated, and the envelope is sealed to form a three dimensional core having an airtight envelope around the core. The three dimensional vacuum core is positioned between a wrapper and a liner, and the wrapper and the liner are interconnected to form a vacuum insulated refrigerator structure.

An airfoil system is provided that includes an airfoil and an electric device. The airfoil includes a first exterior surface, a second exterior surface, a first airfoil segment and a second airfoil segment attached to the first airfoil segment. The airfoil extends widthwise between the first exterior surface and the second exterior surface. The first airfoil segment forms the first exterior surface. The second airfoil segment forms the second exterior surface. The electric device is embedded within the airfoil between the first airfoil segment and the second airfoil segment.

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.

A wiring harness for coupling electronic components includes a hollow trunk sleeve and a hollow branch sleeve. The trunk sleeve includes one or more notches and bends spaced apart along its length. The branch sleeve is interconnected to the trunk sleeve at each corresponding notch, with each branch sleeve open to the trunk sleeve through the respective notch. A bundle of wires extends through the trunk sleeve, with a sub-set of the bundle extending through each notch and corresponding branch sleeve. A first encapsulation layer is disposed about the trunk and branch sleeve at each interconnection separately secures each branch sleeve to the trunk sleeve. A second encapsulation layer is disposed about each bend to maintain the trunk sleeve in a desired pre-defined pattern with each first and second encapsulation layer being separated such that at least a portion of the trunk sleeve is free of the encapsulation layers.

Methods of embedding an elongate susceptor within a thermoplastic body and systems that perform the methods are disclosed herein. The methods include extending the elongate susceptor such that an extended portion of the elongate susceptor extends between a guide structure and a body-contacting structure. The methods also include heating a segment of the elongate susceptor to produce a heated portion of the elongate susceptor. The methods further include pressing a leading region of the heated portion of the elongate susceptor through a body surface of the thermoplastic body and into the thermoplastic body. The methods also include operatively translating at least one of the guide structure, the body-contacting structure, and an application tool that includes the guide structure and the body-contacting structure along an embedment pathway for the elongate susceptor.

To manufacture a shaped object more appropriately by adjusting weight and the like of the shaped object. A manufacturing method for a shaped object for manufacturing a three-dimensional shaped object by depositing a layer of shaping material, the manufacturing method includes: setting a weight of at least part of the shaped object to be a setting weight different from a filling weight that is weight in a case of forming the shaped object by filling deposition material used for deposition; and forming the shaped object to which the setting weight is set to be matched with the setting weight by forming at least part of the shaped object in a state of including a clearance inside as a region that is not formed with the deposition material.

A golf ball of one aspect of the present invention includes a spherical core, one or more cover members to cover the core, and a coating layer to coat a cover member configuring an outermost layer of the one or more cover members.
