20100206421 | FIBER-REINFORCED RESIN PIPE - There is provided an extremely practical fiber-reinforced resin pipe that is lightweight and easy to handle; does not require a weld joint to provide an introduction/outlet part, closure lid, or other component; has excellent corrosion resistance; and is substantially less expensive than a super stainless steel pipe. In a fiber-reinforced resin pipe for introducing and discharging a liquid, a pipe (1) is provided with a plurality of introduction/discharge parts (2) for introducing or discharging liquid that are arranged at intervals in the axial direction from a peripheral surface of the pipe. | 08-19-2010 |
20110052403 | WIND-TURBINE BLADE - A wind-turbine blade that prevents foreign matter from entering the inside thereof during transportation and that can be efficiently assembled in good condition is provided. A wind-turbine blade includes a skin that forms a long and hollow shape, and a main spar that extends in the longitudinal direction and reinforces the skin from the inside thereof. The main spar is divided into a blade-root-side main spar and a blade-tip-side main spar in the longitudinal direction; the blade-root-side main spar and the blade-tip-side main spar have connection sections that are connected to each other; the skin is divided into a connection-section skin, located at a position corresponding to the connection sections, a blade-root-side skin, and a blade-tip-side skin; and openings formed in the blade-root-side skin and the blade-tip-side skin are blocked off by blanking plates. | 03-03-2011 |
20120090718 | TUBE BODY FOR PRESSURE TRANSDUCER - A highly practical tube body for a pressure transducer is provided which has excellent pressure resistance, corrosion resistance, and tensile strength; which can be manufactured at low cost in comparison with cases of using stainless steel; and which makes it possible to keep inside diameter precision high. In this tube body for a pressure transducer, the pressure applied to the interior is varied periodically, and a seal layer ( | 04-19-2012 |

20110171038 | WIND TURBINE ROTOR BLADE AND PRODUCING METHOD OF WIND TURBINE ROTOR BLADE - A wind turbine rotor blade includes an outer skin material formed of fiber-reinforced plastic, main strength materials (super cap materials) disposed on inner surfaces of a back side and a front side of the outer skin material, and crossbeam materials (sheer webs) disposed between the main strength materials, wherein the main strength material is formed by stacking, one on top of another, reinforced fiber sheets having constant widths in a longitudinal direction. | 07-14-2011 |
20120100002 | WIND TURBINE ROTOR BLADE - Provided is a wind turbine rotor blade that can secure a sufficient strength in a coupling portion without significant increase in weight even though a blade is increased in size because beams, which are main strength members of the separated blades, are coupled to each other by metallic coupling members. A wind turbine rotor blade including: a skin that forms a long hollow shape; and a beam that is vertically passed in a longitudinal direction to reinforce the skin from inside, wherein the beam is separated into at least two portions in the longitudinal direction, and ends of the adjacent beams are coupled to each other through a metallic coupling member having: a first flange portion opposed to the one end; a second flange portion opposed to the other end; and a connecting portion that connects these first flange portion and second flange portion, and the skin is separated into a coupling portion skin arranged at a position corresponding to the coupling member, and a main body skin arranged at a position corresponding to the beam. | 04-26-2012 |
20120186730 | REINFORCEMENT FABRIC LAMINATING APPARATUS AND METHOD FOR THE SAME - Provided are a reinforcement fabric laminating apparatus and a method for the same in which wrinkles that occur when a sheet-like reinforcement fabric is laminated on a curved or bent mold can be prevented, the workload can be reduced, and the operating efficiency can be improved. A reinforcement fabric laminating apparatus including a sheet feeding unit that feeds out a reinforcement fabric to be laminated on a mold and a pressure contact unit that pressure-contacts the reinforcement fabric onto the mold, wherein the pressure contact unit has a narrower width than the reinforcement fabric, and the sheet feeding unit supplies the reinforcement fabric while applying tension between the sheet feeding unit and the pressure contact unit. | 07-26-2012 |
20120211476 | CUTTING APPARATUS FOR FIBER-REINFORCED PLASTICS - Provided is a cutting apparatus for fiber-reinforced plastics that reduces an increase in processing cost and also reduces a decrease in the quality of a cut surface. The cutting apparatus includes a laser emitter ( | 08-23-2012 |
20140027960 | METHOD FOR MANUFACTURING COMPOSITE MATERIAL - A reinforced fiber base material is placed on a forming die having a concave part and fixed to the forming die by at least a pair of fixing members disposed on either side of the concave part so as to form a gap between the reinforced fiber base material and a bottom surface of the concave part of the forming die. Subsequently, the reinforced fiber base material fixed to the forming die is covered by a bag film, a forming space that is formed between the forming die and the bag film is decompressed, and a matrix resin is allowed to flow inside the decompressed forming space. The matrix resin is then hardened so as to obtain a composite material in which the reinforced fiber base material and the matrix resin are integrally formed. | 01-30-2014 |
