摘要:
A method and apparatus is provided for manufacturing a carbon fiber woven fabric by opening and closing a warp sheet formed of carbon fiber warps and by injecting wefts made of carbon fibers by water-jet into the warp sheet when the warp sheet is open. The accumulation of fluffs generated by abrasion between the weft and various guides is reduced by interrupting dispersion of water injected from the nozzle onto the weft as the weft travels from a bobbin to the nozzle, by sucking fluffs from the weft, and/or by causing contact between the weft and fluffs on the surface of the nozzle by loosening the weft, thereby making it possible to conduct a high-speed continuous operation.
摘要:
A carbon fiber-made reinforcing woven fabric comprising a carbon-fiber woven fabric formed from warps consisting of carbon fibers and wefts consisting of carbon fibers, and auxiliary yarns arranged along at least either warps or wefts, the auxiliary yarns being passed over and under other yarns differently from associated warps or wefts. When prepreg is produced by applying matrix resin to this woven fabric by a wet/prepreg processing method before drying, the presence of auxiliary yarns in gaps in the vicinities of warp-weft intersections on the woven fabric allows matrix resin to remain around auxiliary yarns to produce no apertures in the obtained prepreg, whereby the woven fabric is suitable for a prepreg production by wet/prepreg processing.
摘要:
A stitched laminate, in which plural sheets respectively having plural tow-like carbon fibers arranged in parallel to each other are laminated, with the orienting directions of the carbon fiber yarns of the respective sheets kept at different angles against a reference direction, and are stitched integrally using stitching threads. The fineness of each of the carbon fiber yarns is in a range of 1,200 to 17,000 Tex, and the pitch of the arranged carbon fibers yarns is in the range of 8 to 60 mm. In the sheets, the arranged carbon fiber yarns are widened in yarn width to ensure that no gap substantially exists between the respectively adjacent carbon fiber yarns. The plural carbon fiber yarns supplied to form sheets are respectively brought into contact with plural rollers, to be bent and widened in yarn width.

The plurality of flat warps are reeded to a desired density in relation to the arranged direction. The warps are then twisted along the longitudinal travelling direction so that the flat surfaces of the individual flat warps are oriented to the arranged direction.
