Provided is a joint manufacturing method including: a step A of preparing a laminate in which two objects to be joined are temporarily adhered with a heat-joining sheet including a pre-sintering layer interposed between the two objects to be joined; a step B of increasing a temperature of the laminate from a temperature equal to or lower than a first temperature defined below to a second temperature; and a step C of holding the temperature of the laminate in a predetermined range after the step B, in which the laminate is pressurized during at least a part of the step B and at least a part of the step C. The first temperature is a temperature at which an organic component contained in the pre-sintering layer is decreased by 10% by weight when the pre-sintering layer is subjected to thermogravimetric measurement.

A vacuum probe comprises a sharpened body that is displaceable downward and toward a vacuum bag during vacuum hose quick connection. The sharpened body and a valve element inside the vacuum probe move in tandem until the sharpened body projects outside the vacuum probe. A vacuum pressure applied via the vacuum hose pulls the vacuum bag upwards and towards the projecting sharpened body, which then punctures the vacuum bag, thereby enabling air under the vacuum bag to be evacuated via the vacuum probe as vacuum pressure continues to be applied.

A preparation method of a loose lay plastic floor includes the following steps: (a) subjecting a wear layer, a printing layer, a semi-rigid PVC layer, a core layer and an adsorption layer to hot-melt compounding and shaping to obtain a composite board; (b) coating one or more layers of UV coating on a surface of the wear layer of the composite board; and (c) subjecting the composite board coated with the UV coating to tempering, conditioning and punching to obtain a loose lay plastic floor. The core layer is a stone plastic core (SPC), a wood plastic core (WPC), a high density fiberboard (HDF), or a medium density fiberboard (MDF).

The invention provides a method for manufacturing a curved surface shell of an electronic device, which comprises the steps of preparing a translucent base shell having a decorative film; fixed-point hot pressing the decorative film to attach and position the decorative film on an inner surface of the translucent base shell; placing the translucent base shell in a vacuum sealed space to tightly bonding the decorative film to the translucent base shell; and hydraulic pressing the decorative film by high pressure and high temperature so as to be smoothly bonded to the inner surface of the translucent base shell in a liquid solvent.

A method for bonding a first component to a second component includes placing the first and second components in a cavity. Each of the first and second components has a bonding portion, and the bonding portion of the first component faces the bonding portion of the second component. A supercritical fluid is then introduced into the cavity with a temperature of 40-400 C. and a pressure of 1,500-100,000 psi, and a pressure of 4-100,000 psi is applied on both the first and second components, assuring the bonding portion of the first component bond to the bonding portion of the second component. Moreover, a method for separating a first component from a second component includes placing a composite in a cavity. The composite includes the first component, the second component and a connecting layer by which the first component joins to the second component. The supercritical is then introduced into the cavity.

A lamination apparatus including a first stage including a first body portion and an accommodation portion disposed on a bottom surface of the first body portion, a second stage disposed to face the first stage, and a jig device disposed between the first stage and the second stage, the jig device including a second body portion and at least one jig portion, in which the at least one jig portion has one end fastened to the second body portion and the other end having a rounded shape.

The present invention relates to a luminous vehicle sunroof that includes a first glazing with first and second main faces, a light-emitting element such as an OLED or QLED and a collimating optical system with one or more optical films.

An integrated panel made of interconnected laminates includes stacked first and second metal layers (5, 5, 5) and fibre-reinforced adhesive layers (19) between adjacent metal layers. At the location of the transition from the outer surface (7) of the first outer metal layer (5) to the outer surface (7) of the second outer metal layer (4) is located a filler (11). The panel further includes a cladding layer (14), which includes at least one fibre material layer (15, 24) that extends over the filler (11) and the adjacent outer surface regions (12, 13) of the outer metal layers (5, 4) located on opposite sides and which are adhered to the outer surface regions.

A decorative sheet includes a releasing layer, a pressure-sensitive adhesive layer disposed on a surface of the releasing layer, and a skin layer disposed on a surface of the pressure-sensitive adhesive layer. The releasing layer includes a shape-holding layer, both the shrinkage ratio of the shape-holding layer and the shrinkage ratio of the skin layer are 0/1000 to 9/1000, and both the softening start temperature of the shape-holding layer and the softening start temperature of the skin layer are 60 C. or more and 120 C. or less.

A repair patch includes a composite material to repair a a repair target of a composite material. The repair patch includes bonding surfaces which face a bonded surface of a counterbored hole formed in the part to be repaired, and are bonded to the counterbored hole; and an opposite surface opposite to the bonding surfaces in a thickness direction. The opposite surface has a curved plane with a first surface side curvature radius protruding toward the opposite surface in a cross section cut along a plane intersecting an axial direction in the opposite surface. The bonded surface has a curved plane with a second surface side curvature radius protruding toward the bonding surfaces facing the bonded surface in a cross section cut along a plane intersecting an axial direction in the bonded surface. The first surface side curvature radius is smaller than the second surface side curvature radius.
