CARBON-FIBER PREFORM AND CARBON-FIBER-REINFORCED PLASTIC |
| 摘要 |
According to the present invention, a carbon-fiber preform for a carbon-fiber-reinforced plastic is formed from mutually intersecting warp and weft each of which including a carbon-fiber multifilament yarn. At least one of layer surfaces has fluff formed by cutting some of filaments of the carbon-fiber multifilament yarn, and a total fluff length of fluff formed on the warp and a total fluff length of fluff formed on the weft are not equal. The present invention provides a CFRP in which the delamination strength (interlaminar shear strength) is improved and that has a high strength. |
