Various components and methods related to a leading edge assembly are disclosed. The leading edge assembly can include an outer strike shell and a foam core. The foam core can be located inside the outer strike shell. The leading edge assembly can include a heating element with a plurality of sensors and wires. A method of manufacturing a leading edge assembly can include forming a composite layer, applying a metallic layer to the composite layer, installing an electronic device, and inserting a foam core into a cavity bounded by the composite layer and/or the electronic device.

A slot liner for a stator assembly in one embodiment includes a mesh structural member and a coating. The coating is disposed on at least one side of the mesh structural member, and includes a mixture of a filler and a polyimide resin. The filler is a high thermal conductivity electrical insulating (HTCEI) filler, and includes particles of at least one of boron nitride, aluminum nitride, or a diamond material.

A solenoid valve device may include a rod pin; a cylindrical core comprising a magnetic material and arranged around the rod pin; a bobbin comprising resin and arranged to cover a side surface of the cylindrical core; a coil wound around the bobbin; a case comprising a bottom and being cylindrical and having an opening at one axial end thereof, and arranged to accommodate the rod pin, the cylindrical core, the bobbin, and the coil; a nozzle comprising resin and attached to a case opening portion defined at the one axial end of the case; a first a second port each defined in the nozzle; a valve body arranged in the nozzle, and structured to be driven by the rod pin to open or close a communication between the first and second ports; and a tubular metal cover arranged to cover a lateral surface of the nozzle.

The present disclosure is directed to pre-cured composites for use in manufacturing rotor blade components of a wind turbine. In one embodiment, the pre-cured composites are pultruded composites having a continuous base portion with a plurality of integral protrusions extending from the continuous base portion, and a fabric layer cured with the continuous base portion. Further, adjacent protrusions are separated by a gap.

A polymeric product including at least two layers, wherein a functional layer includes a polymeric material and at least one anti-microbial substance, and a protective layer, including a polymeric material arranged outside the functional layer and completely covering the functional layer, wherein the protective layer does not include any anti-microbial substances. A method of producing the product, the use of the same and a kit for producing the product.

A method for producing a body structural element, which can be a roof bow for a motor vehicle, consists of a main body made of fibre-reinforced plastic and a metal connection part. In one or more embodiments, the method includes preparing the metal connection part, preparing a fiber-plastic matrix semifinished product from a duromer resin system and carbon fibers, and overlapping the metal connection part and the fiber-plastic matrix semifinished product in a compression mold. In certain embodiments, the method further includes compressing the metal connection part with the fiber-plastic matrix semifinished product until a fiber-plastic matrix molding material penetrates into undercuts of the metal connection part, and then curing the fiber-plastic matrix semifinished product to form the main body made of fiber-reinforced plastic, wherein the main body is connected in a form-fitting manner to the metal connection part.

A method for fabricating a composite object with a computer-controlled apparatus, and the apparatus therefor. The comprises a reservoir containing liquid, curable first material, means to selectively solidify the first material and means to selectively deposit a second material. The method involves the steps of selectively depositing portions of the second material, and selectively solidifying portions of the first material, such that the solidified portions of the first material and the deposited portions of the second material form the composite object.

A process for manufacturing a ceramic matrix composite component, said process comprising inserting at least one fibrous sheet into a resin transfer molding system. The process includes wetting the at least one (dry or partially wetted) fibrous sheet with a neat first pre-ceramic polymer resin. The process includes injecting a second pre-ceramic polymer resin including a filler material into at least one fibrous sheet and curing the pre-ceramic polymer resin.
