A fiber-reinforced resin molded article is produced by pressing a plurality of thermoplastic base material sheets, each of which contains a plurality of reinforcing fibers, in a stacked state where the base material sheets are stacked so that the fiber directions (orientation direction of the reinforcing fibers) are alternated. Each base material sheet is provided with a cut including: a plurality of lengthwise cut lines extending parallel to the fiber direction; and a plurality of crosswise cut lines extending parallel to a direction that is perpendicular to the fiber direction. A plurality of cut interruption parts for interrupting the lengthwise cut lines in the fiber direction are formed. The cut interruption parts are arranged in a staggered manner so as to be displaced from each other in the fiber direction.

A method for manufacturing a composite structure having first and second structural members includes the steps of: (A) placing a plate in a forming mold having a first molding member, and a second molding member with an injection hole; (B) moving the first molding member toward the second molding member to stamp and deform the plate; (C) injecting a molten substrate onto the plate via the injection hole to stamp and deform again the plate so as to form the first structural member; (D) removing an assembly of the first structural member and a solidified substrate from the first molding member; and (E) removing an excess part of the solidified substrate to form the second structural member.

Annular structures formed using composite materials and systems and methods for forming annular structures using composite materials are provided. The composite materials can include fiber reinforced thermoplastic materials. The annular structures include a number of component parts. Each component part can be in the form of a strip of fiber reinforced thermoplastic material that extends around all or a portion of a circumference of the structure. The ends of the component parts can be staggered, so that they a placed at different locations about the circumference of the structure. Methods for forming annular composite structures include wrapping one or more strips of fiber reinforced thermoplastic material having one or more layers about a mandrel, and fusing the strips to form an integral annular structure.

Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle.

Disclosed herein are fully automated methods for shaping a composite material.

Disclosed are a pouch film shaping apparatus including a preheating lamp configured to preheat a metal barrier layer of a pouch film in order to increase stretching force of the pouch film and a pouch film shaping method.

An apparatus for forming pre-shaped insulating sheets comprises a first bending station and a second bending station. The first bending station is used for bending a flat sheet of insulating material into a Z-shaped sheet (5). The second bending station is used for bending the Z-shaped sheet into an S-shape. The first and second bending stations comprise pairs of first (13a, 13b) and second bending operators for creating bending movements.

Provided are a method and an apparatus for manufacturing a fiber-reinforced resin molding material by which, when the fiber-reinforced resin molding material is manufactured, separated fiber bundles can be supplied to a cutting machine in stable condition while avoiding the influence of meandering of the fiber bundles or slanting or meandering of filaments occurring in the fiber bundles. A method for manufacturing a sheet-shaped fiber-reinforced resin molding material in which spaces between filaments of cut-out fiber bundles (CF) are impregnated with resin includes, so that a condition of the following expression (1) is satisfied, intermittently separating fibers of the continuous fiber bundles (CF) in a longitudinal direction by a rotational blade (18) serving as a fiber separating part and cutting out the fiber bundles with an interval therebetween in a longitudinal direction of a cutting machine (13A) to obtain the cut-out fiber bundles (CF). Expression (1): 1≤a/L (where a represents a length of a separated part of the continuous fiber bundles (CF) and L represents an interval when the fiber bundles (CF) are cut out in the longitudinal direction.)

Systems, apparatuses, and methods to secure a film to a container are provided. An example sealing device utilizes film from a supply of film to seal a lid onto a container. Various sizes of containers are usable with some example sealing devices. Additional features, such as printing on the film and piercing the film for ventilation and/or insertion of a straw are contemplated. One or more markings along the film may be utilized for confirming that an approved film has been loaded into the sealing device. In response, various components or features of the sealing device may be appropriately enabled or disabled. The one or more markings may also be utilized to convey data to the sealing device regarding the installed film, such as for improved operation thereof.

A method for forming cellulose products from an air-formed cellulose blank having a base and one or more forming moulds attached to the base which is arranged to rotate around a rotational axis, wherein each forming mould comprises a first mould part Wand a corresponding second mould part wherein during rotational movement of the base around the rotational axis each first mould part is arranged to engage with its corresponding second mould part in a pressing direction. The method comprises arranging the cellulose blank in a position between a first mould and the second mould forming the cellulose products in the rotary forming mould system, by applying a forming pressure between the first mould and its corresponding second mould through an engaging movement of the first mould in relation to its corresponding second mould in the pressing direction, wherein the forming moulds are rotating with the base around the rotational axis.
