A resin sheet production method includes a preparation step of preparing a resin molding sheet including a base and a thermally expansive layer that is formed on one main surface of the base, the thermally expansive layer including a thermally expandable material; a heat conversion layer forming step of forming a heat conversion layer that converts electromagnetic waves to heat on at least one of the first main surface of the resin molding sheet or a second main surface on a side opposite to the first main surface; a pre-heating step of heating the resin molding sheet on which the heat conversion layer is formed to a temperature that is lower than an expansion starting temperature at which the thermally expandable material starts to expand; and a main heating step of irradiating the heat conversion layer of the resin molding sheet that is heated in the pre-heating step with the electromagnetic waves to cause the heat conversion layer to distend, thereby causing the base to deform and forming a shaped object on the resin molding sheet.

The objective of the present invention is to provide a mold-release film that docs not contaminate the mold or the formed body. This invention provides a mold-release film comprising a base material layer formed from a thermoplastic resin, and a surface layer formed from a resin composition layered on at least one surface of the base material layer. The mold-release film has a trouser tear strength, conforming to JIS K 7128-1, of 5 N/mm or stronger. The resin composition has a peel strength of 15 mN/30 mm or weaker, as measured at 175 C. in accordance with JIS Z0237. The resin composition has an elongation at break of 70% or greater, as measured at 175 C. in accordance with JIS K 7127.

A system for the continuous extrusion, molding, and curing of tread rubber is provided. A plurality of discrete mold sectors are arranged adjacent to each other along a longitudinal axis between an in-feed and an out-feed of a mold sector transport mechanism that extends through a heated press. As the mold sectors are continuously advanced along a process direction in steps, rubber material is extruded and placed onto at least one of the mold sectors near the in-feed end such that an elongated strip of rubber material extends over multiple mold sectors along the longitudinal axis. As the strip of rubber material exits the press, the mold sectors are sequentially removed from the rubber material and returned to the in-feed. An extruder outlet positioned near the in-feed can be moved towards or away from the mold sectors to supply rubber material and prevent backflow.

The invention relates to a method for producing a fiber-plastic composite reference body for simulating delamination for the nondestructive testing of FPC components, in particular aircraft components, comprising the following steps: i. producing a first insert by a. arranging a first FPC layer; b. forming a recess in the first FPC layer; c. procuring the first FPC layer, in order to obtain the first insert; ii. producing a second insert by a. arranging a second FPC layer; b. pre-curing the second FPC layer, in order to obtain the second insert; iii. providing at least one first FPC layer and at least one second FPC layer with a first clearance and a second clearance; iv. inserting the first insert and the second insert into the respective clearance of the corresponding FPC layer; v. curing the arrangement, a delamination being simulated at the recess of the first insert.

A determination device used in a shaping device in which a three-dimensional shaped object is shaped on an upper surface of a film adhered to a pallet, the determination device determining whether the film is adhered to the pallet based on imaging data of the pallet.

A system and method for removing a backing from a ply of composite material is disclosed. The system includes a roller having a roller axis and a roller surface that circumscribes the roller axis. The system also includes an adhesion feature disposed on the roller surface. The system further includes a roller drive to move the roller along a travel path that is perpendicular to the roller axis and to rotate the roller about the roller axis.

A PVB film for HUD, a forming mold and a forming method thereof are presented. The accuracy error of HUD imaging achieved by the PVB film for HUD is 0.1 mrad. The forming mold includes an upper mold and a lower mold, the two of which can form an enclosed mold cavity when clamped together, wherein protective films are disposed on inner surfaces of the upper mold and the lower mold, respectively, for supporting PVB material and preventing the PVB material from bonding with the upper mold and the lower mold, and wherein shapes of the protective films match shapes of the upper mold and the lower mold.

A method of manufacturing a sandwich panel (100) includes: a step of preparing a plurality of sheet-like prepregs (211); a step of performing a first heating and pressurization process through a release film (25) on upper and lower surfaces of a laminate where the plurality of prepregs (211) are laminated such that the laminate is integrated to obtain a composite facing material (40); and a step of disposing the composite facing material (40) on each of an upper surface side and a lower surface side of a sheet-like core layer (10) having a honeycomb structure and integrating the laminate through a second heating and pressurization process, in which a pressure of the first heating and pressurization process is higher than or equal to a pressure of the second heating and pressurization process.

A plant for the production of slabs from a mixture of agglomerate comprises a station (50) with a mixture distribution unit (52) which pours the mixture onto the inner surface of a slab forming mould (11) present in the station. The mould (11) is provided with a sheet (15) of plastic protective material arranged above the inner surface of the mould and which forms the surface for contact with the mixture which is introduced into the mould by the distribution unit (52). The station comprises air suction means which are coupled/connected to suction ducts (54) which are present in the mould and which emerge with their front end inside the mould in a zone of the mould situated between the inner surface of the mould and the sheet (15), so as to allow the suction of air between the sheet and this inner surface and bring the sheet (15) against this surface by means of a vacuum. A method for the production of slabs is also described.

A method for preparation of a mold (10) intended to form a slab from a mixture of agglomerate comprising the steps of depositing over the mold surfaces a sheet (15) of PVA-based plastic material so as to form with it a surface for subsequent contact with the mixture introduced into the mold for forming the slab, whereby in at least some areas a layer (14) of a fluid agent containing PVA in a solution is interposed between the sheet (15) and the mold surfaces. A plant for carrying out the method and a method for production of a slab are also described.
