An apparatus for cold-shaping a glass sheet that includes: a plurality of vacuum chucks configured within a moveable table; a first automated pick mechanism proximate the table; an automated dispensing mechanism proximate the table; and a pressing apparatus. The first pick mechanism is configured to shape a glass sheet onto one of the chucks. The dispensing mechanism is configured to dispense a curable adhesive onto the glass sheet or a frame. One of the first pick mechanism and the dispensing mechanism is configured to position the frame onto the glass sheet such that the adhesive is disposed between the glass sheet and the frame. The pressing apparatus is configured to press the frame and the adhesive onto the glass sheet to define a finished glass sheet assembly. The glass sheet is bendable at ambient temperature. Methods for cold-shaping a glass sheet are also included in the disclosure.

A method for manufacturing a structural element of a wind turbine blade including forming of at least one injection hole in at least one laminate provided on a top side of a core material of a first portion and a second portion of the structural element and a bottom side of a core material of the first portion and the second portion, so that the at least one injection hole is fluidically connected to the cavity. Further, injecting adhesive through the injection hole into the cavity, curing the adhesive injected into the cavity and thereby forming a joint between an end of the core material of the first portion and an end of the core material of the second portion. Further, a method for manufacturing a wind turbine blade and the structural element, the wind turbine blade is also provided.

A method for manufacturing a blade shell part of a wind turbine blade includes providing a mould for manufacturing a blade shell part of the wind turbine blade. The mould has a first moulding side with a first moulding surface that defines an outer shape of the blade shell part. The method comprises providing a blade shell part on the first moulding surface and providing a support element and attaching the support element to a fastening section of the blade shell part. Attaching the support element includes applying adhesive between the support element and the fastening part. The method also includes providing an air heating assembly having a cover extending in a longitudinal direction between a first cover end and a second cover end and extending in a transverse direction between a primary cover end and a secondary cover end, the cover defining a cavity.

Illustrative examples of forming and using suitably adapted materials for improving interface strength between thermoset-thermoplastic joined parts includes exposure of a thermoplastic substrate to a plasma to form an amine-functionalized substrate having amine chemical moieties disposed on a first surface. The first surface of the thermoplastic substrate is positioned adjacent to and contacts a second surface of a thermoset substrate to form a workpiece. The thermoset substrate includes epoxide chemical moieties on and within material forming the thermoset substrate. The workpiece is subsequently heated to form a structure, where heating of the workpiece causes covalent chemical bonds to form between the plasma-treated first surface of the thermoplastic substrate and the second surface of the thermoset substrate. Thereafter, additional thermoplastic components can be fusion bonded to a surface of the thermoplastic substrate opposite the first surface—thereby providing improved attachment of additional thermoplastic components to the thermoset substrate.

Systems for positioning and bonding a nutplate to a substrate having an aperture include a nutplate engagement fixture and a temperature sensor retention fixture. The nutplate engagement fixture includes a rigid tube and an elastomeric tube engaged with the rigid tube, the elastomeric tube having an elongated tube sized to provide a friction fit with the aperture and retain the elastomeric tube within the aperture. The rigid tube is operable to engage the nutplate at one end and the elastomeric tube is configured to anchor the nutplate engagement fixture at the aperture and secure the nutplate in contact with the substrate. The temperature sensor retention fixture includes a fixture body sized and configured to engage with the nutplate and at least one passageway within the fixture body sized and configured to allow a temperature sensor to be inserted or embedded therein with an end proximal a surface of the nutplate.

Systems and methods for making an antenna reflector. The methods comprise: obtaining a Carbon Nano-Tube (“CNT”) material; cutting the CNT material into a plurality of wedge shaped pieces; and bonding together the wedge shaped pieces using a resin film adhesive to form the antenna reflector with a three dimensional contoured surface.

The present invention relates to a synthetic leather for a steering wheel cover of a vehicle, and a method for preparing the same. The synthetic leather including a fiber base layer (101) including a microfiber nonwoven fabric, an urethane porous layer (102) formed on the fiber base layer, a polyurethane resin skin layer (104) formed on the urethane porous layer, and prepared by polymerizing an isocyanate compound and a polyol compound including polycarbonate-based polyol, fluorine-based polyol and ester-based polyol, and an adhesive layer (103) for adhering the urethane porous layer and the skin layer.

Described herein are methods of forming uncured sealant assemblies and also methods of forming seals between various parts using such assemblies. In some examples, an uncured sealant assembly comprises two protective layers and an uncured sealant layer, disposed in between. The uncured sealant assembly is stored and provided at a cure-inhibiting temperature, selected to minimize the curing rate of the uncured sealant layer. The size and the shape of the uncured sealant layer are specifically selected to ensure the complete coverage of the faying surfaces, filling of all gaps and voids between the faying surfaces, and controlling the shape and size of uncured sealant squeeze out between the faying surfaces. In some examples, the size and shape of the uncured sealant layer maybe be specifically selected to have no uncured sealant squeeze out between parts.

A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including a tubular liner wetted with a curable compound; introducing fluid into the inflatable bladder to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition; measuring a flow rate and a temperature of the fluid entering the bladder; calculating a time period sufficient for the tubular liner to cure based on: an amount of heat required for curing, based on dimensional information of the liner, and the measured flow rate and temperature of the fluid; and maintaining the liner assembly in an inflated condition for the time period sufficient for the tubular liner to cure.
