The switching knob includes a disk-like switching knob body provided with a tab portion protruding in a thickness direction of the switching knob body, and a maximum height position at which a height of the tab portion is maximum is positioned outward of a center position of the switching knob body in a radial direction of the switching knob body.

Methods for repairing composite component voids are provided. For example, one method comprises locating a void in a composite component and subjecting the composite component to a process for repair. The process for repair includes creating a flow path through the void, applying a filler material to the composite component at the flow path, and processing the composite component having the filler material. In some embodiments, the flow path has a first opening on a first side of the composite component and a second opening on a second, opposite side of the composite component. In other embodiments, at least one portion of the flow path extends at a first angle with respect to a lateral direction defined by the CMC component, and at least another portion extends at a second angle with respect to the lateral direction.

Embodiments of the present disclosure provide a splicing nano-imprint template, a repair method of a splicing seam thereof, and a manufacturing method thereof. The repair method of the splicing seam of the splicing nano-imprint template includes: providing a splicing nano-imprint plate, in which the splicing nano-imprint plate includes a base substrate and splicing modules that are positioned on the base substrate, a splicing seam is provided between adjacent spicing modules, and each of the splicing modules includes a unit pattern; forming a repair adhesive layer at least at the splicing seam; and performing a patterning process on the repair adhesive layer to form a repair module, in which the repair module includes the unit pattern.

A method of repairing a composite structure includes providing an assembled composite structure comprising a substantially rigid outer component, wherein the composite structure comprises a void space at least partially bounded by the outer component. The method further includes forming an injection hole through the outer component to provide a path between the void space and space external to the composite structure. The method further includes injecting foam into the void space through the injection hole while the foam is in a substantially unexpanded state and expanding the foam within the void space.

A method for repairing composite components includes positioning repair material within a repair region of a composite component formed of a composite material. Furthermore, the method includes heating the repair region to a first temperature. Additionally, the method includes heating a remaining portion of the composite component to a second temperature. Moreover, the method includes melt infiltrating the repair region with an infiltrant to densify the repair material. The first temperature is at or above a melting point of the infiltrant and the second temperature is less than the melting point.

Technology for controlling in-vehicle three dimensional (3D) printer(s) that replenish road engaging surfaces of the vehicle assembly. In some embodiment the 3D printer is controlled to replenish the road engaging surface while the vehicle is being driven. In some embodiments, an Internet of Things (IoT) sensor is used to detect wear on the road engaging surface to help control the location(s) where the 3D printer adds the additive material.

Embodiments are directed to a radiopaque foam used to repair composite structures. A method for creating the radiopaque foam comprises providing first and second resin components that are radiolucent to x-ray imaging. A barium sulfate component is combined with the second resin component. After combining the barium sulfate component and the second resin component, the first resin component and the second resin component are mixed to create a pourable foam. An amount of barium sulfate combined with the second resin component is sufficient to render the pourable foam radiopaque to x-ray imaging.

A method of sealing surface imperfections on a sanded surface of a repair to a vehicle body is provided that includes an uncured layer of a formulation being applied to sanded cured body filler on the vehicle body. The formulation includes a polyester resin, a crosslinking agent, a solvent, and a particulate filler. The uncured layer is exposed to actinic radiation to induce cure of the uncured layer to form a sealing coating. The resulting seal coating has able to seal surface imperfections. A surface imperfection sealing formulation is also provided that includes a polyester resin and a multifunctional crosslinking agent. A solvent is provided. A photoinitiator renders the formulation curable upon exposure to ultraviolet light exposure. A particulate filler is also present in an amount to result in a formulation with an uncured viscosity of between 2600 and 3000 centipoises.
