20110287213 | PROCESS AND APPARATUS FOR PRODUCING REINFORCING-FIBER STRIP SUBSTRATE HAVING CIRCULAR-ARC PART, AND LAYERED STRUCTURE, PREFORM, AND FIBER-REINFORCED RESIN COMPOSITE MATERIAL EACH COMPRISING OR PRODUCED USING THE SUBSTRATE - A process for producing a reinforcing-fiber strip substrate having a circular-arc part includes contacting one surface of a strip-shaped, unidirectional reinforcing-fiber substrate formed by arranging a plurality of reinforcing-fiber strands in one direction in parallel with each other with a flexible member; deforming the unidirectional reinforcing-fiber substrate into a circular-arc shape by deforming at least a part of the flexible member into a circular-arc shape in a direction extending along its contact surface with the unidirectional reinforcing-fiber substrate; and thereafter, separating the flexible member from the unidirectional reinforcing-fiber substrate having been deformed. | 11-24-2011 |
20120175049 | PROCESS, AND APPARATUS, FOR PRODUCING REINFORCING FIBER MOLDING - A method of forming, on a strip-shaped laminate of multiple reinforcing fiber sheets superimposed one upon another, two flexures with respect to the cross-section configuration thereof, wherein in the forming of the two flexures with the use of two flexure forming dies independent from each other, respectively, the two flexure forming dies are arranged so that the relative distance of the two flexure forming dies is changeable in the direction perpendicular to the longitudinal direction of the strip-shaped laminate. This method can be effectively utilized in the production of a reinforcing fiber molding with changing of the distance between the two flexures namely, width of web portion or gauge between two flange portions from the strip-shaped laminate, or the production of fiber reinforced resin (FRP) molding therefrom. | 07-12-2012 |
20120196083 | PROCESS AND APPARATUS FOR PRODUCING BEAM MEMBER - A process for producing a beam member formed by a reinforcing fiber base material which has a web portion and at least a pair of flange portions extending to both sides via at least a branching point from the web portion, at a cross-sectional surface orthogonal to a longitudinal direction of the beam member, and by a shaped filler which fills a gap having a wedge shape formed at the branching point, is provided. The shaped filler is produced by: (A) a filler supply process for supplying a filler member configured by reinforcing fibers; (B) a preshaping process for providing a preshaped filler having at least a wedge projection portion, by pressurizing the filler member by a preshaping mold; and (C) a filler deforming process for providing a shaped filler by deforming the preshaped filler. | 08-02-2012 |

20130240150 | PREFORM FOR MOLDING FIBER-REINFORCED RESIN BEAM, PROCESS FOR PRODUCING THE SAME, APPARATUS FOR PRODUCING THE SAME, AND PROCESS FOR PRODUCING FIBER-REINFORCED RESIN BEAM - A preform for the molding of a fiber-reinforced resin beam, the preform comprising: a reinforcing-fiber beam which has been formed from a reinforcing-fiber base made up of many reinforcing fibers and has a cross-sectional shape comprising at least one linear part and at least one curved part connected to the linear part; and a release sheet bonded and united through an adhesive resin to at least part of a surface of the reinforcing-fiber base along the lengthwise direction for the base. A process for producing a preform comprises: a step in which a continuous flat reinforcing-fiber base having a release sheet bonded and united to a surface thereof is shaped so that the cross-sectional shape of the base comes to have a curved part to thereby produce a preshaped object; and a preshaped-object uniting step in which the preshaped object is bonded and united to another preshaped object. | 09-19-2013 |
20140186575 | PROCESS AND APPARATUS FOR PRODUCING REINFORCING-FIBER STRIP SUBSTRATE HAVING CIRCULAR-ARC PART, AND LAYERED STRUCTURE, PREFORM, AND FIBER-REINFORCED RESIN COMPOSITE MATERIAL EACH COMPRISING OR PRODUCED USING THE SUBSTRATE - A process for producing a reinforcing-fiber strip substrate having a circular-arc part includes contacting one surface of a strip-shaped, unidirectional reinforcing-fiber substrate formed by arranging a plurality of reinforcing-fiber strands in one direction in parallel with each other with a flexible member; deforming the unidirectional reinforcing-fiber substrate into a circular-arc shape by deforming at least a part of the flexible member into a circular-arc shape in a direction extending along its contact surface with the unidirectional reinforcing-fiber substrate; and thereafter, separating the flexible member from the unidirectional reinforcing-fiber substrate having been deformed. | 07-03-2014 |
20150048555 | CARBON FIBER PREFORM, CARBON FIBER-REINFORCED PLASTIC AND MANUFACTURING METHOD OF CARBON FIBER PREFORM - A carbon fiber preform has a plurality of carbon fiber sheets that are stacked and are bonded to each other by means of an adhesive resin having thermal plasticity. This carbon fiber preform comprises a partial-conducting layer arranged at least either between at least one pair of adjacent layers of the plurality of carbon fiber sheets or on a surface area of the plurality of carbon fiber sheets and configured to have a resistance area which has higher electric resistance than electric resistance of the carbon fiber sheet in a stacking direction and a conductive area which is capable of having electrical continuity in the stacking direction, wherein the resistance area and the conductive area are arranged in a surface direction orthogonal to the stacking direction. The plurality of carbon fibers sheets are bonded to each other by means of the adhesive resin in the surface direction in the conductive area and in an area corresponding to periphery of the conductive area. In areas other than the conductive area and the area corresponding to the periphery of the conductive area, the plurality of carbon fiber sheets are not bonded to each other by means of the adhesive resin. | 02-19-2015 |
20150091212 | GATE VALVE AND MANUFACTURING METHOD OF GATE VALVE - A gate valve is configured to have a first fluid flow path. In a state where a gate valve pin is at a first pin position, a front end section on an injection hole side of the gate valve pin closes an injection hole. In a state where the gate valve pin is at a second pin position that is more distant from the injection hole than the first pin position, a front end section opens the injection hole to make communication between the first fluid flow path and the injection hole and thereby form a resin supply line. In a state where a sleeve is at a first sleeve position and the gate valve pin is at the first pin position, a second fluid flow path is formed in the gate valve to connect an injection hole-side end of the first fluid flow path to outside of the gate valve and is made to communicate with the first fluid flow path and thereby form a cleaning line. | 04-02-2015 |
