The invention relates to a method for manufacturing vacuum insulation panels with a fiber core, comprising the steps of: providing a core blank of fibers, compressing the core blank to a predetermined final thickness for forming the core, evacuating a foil sleeve enclosing the core up to a pressure of ≦1 mbar, and sealing the foil sleeve. The method according to the invention is characterized by the fact that, in the compression step, the core blank is arranged between two cover elements and is mechanically compressed therebetween, that the core is kept under compression pressure until the foil sleeve is sealed, and that the compression step is performed at the place of manufacture at room temperature without thermal impact. Thus, a method for manufacturing vacuum insulation panels with a fiber core can be improved such that it can be performed with reduced energy requirement and yet the insulating effect of the vacuum insulation panels does not suffer therefrom.

The present invention relates to an apparatus for adhering a soft slab and a covering material together. The apparatus for adhering the soft slab and the covering material together includes: a moving unit consisting of a plurality of rollers for moving the soft slab; a conveyor unit including a belt configured such that air passes through the top and bottom surface thereof, and a driving unit for driving the belt, the conveyor unit being intended for transferring a covering material seated on the top surface of the belt toward an adhesive surface of the soft slab; and an air suction unit provided at the bottom surface of the belt so as to suction air such that the covering material is tightly attached onto the top surface of the belt, thereby attaching the covering material onto the adhesive surface of the soft slab without generating pleats.

A method for producing an aircraft structural component includes the steps of introducing a plurality of semi-finished product layers for producing a component from a fibre-reinforced, thermoplastic plastic material into a compression mould, applying pressure to the stacked semi-finished product layers, the stacked semi-finished product layers being fixed, before pressure is applied, at particular points in their position in the compression mould and/or relative to one another in such a way that, while pressure is being applied to the semi-finished product layers stacked in the compression mould, a sliding movement of the semi-finished product layers relative to one another and/or relative to the compression mould, preventing wrinkling in the semi-finished product layers, takes place, and removing the aircraft structural component from the compression mould.

A method of making a core-stiffened structure includes the steps of providing a honeycomb core having an adhesive disposed on first and second surfaces thereof, providing a first skin and a second skin, and assembling the first skin, the second skin, and the honeycomb core to form the core-stiffened structure. The method further includes the steps of curing the core-stiffened structure and inhibiting at least one of the first skin and the second skin from protruding into at least one cell of the honeycomb core during the step of curing the core-stiffened structure.

The performances and durability of a diaphragm sheet of a solar cell laminator are enhanced, and a favorable lamination work is stably performed over a long period of time. In addition, by stably performing sufficient and uniform lamination over a long period of time, a high-quality module is stably manufactured over a long period of time. A solar cell module is manufactured by using a diaphragm sheet formed of a composition containing an ethylene-propylene-diene rubber (EPDM), which is low in creep deformation and high in durability against an organic peroxide and a silane coupling agent.

A tool (10) for laminating a metal foil (23) and polymer film (25) to form a laminate structure (20) is disclosed. A method of using the tool (10) to form a laminate structure (20) is also disclosed. The tool (10) comprises movable platens (11) having sealing surfaces (12) which form a cavity (19). The cavity (19) is pressurized and heated to form the laminated structure (20) and evacuated to remove volatiles from the structure (20).
