    摘要： To provide an optimum woven fabric most suitable as a base cloth for airbags whose selvage waving has been reduced by restraining recession of a weaving shed of a selvage end portion during the high-density woven fabric weaving and which is excellent in processing passing property and uniform application property in the steps of scouring, setting and coating, and which is also excellent in cuttability and sewability, and a process for producing the woven fabric. This woven fabric is a woven fabric that uses a synthetic fiber multifilament yarn as a ground yarn, and that includes in a selvage weave portion at an end portion of the woven fabric a binding yarn composed of a filament having a fineness of 33 dtex or less and an additional yarn composed of a filament having a fineness of 33 dtex or less as well as a selvage-tightening yarn composed of a multifilament having a total fineness that is 80% or greater of the total fineness of the ground yarn. The production process, in order to form a selvage weave portion present at an end portion of the woven fabric, uses filaments having a fineness of 33 dtex or less as a binding yarn and an additional yarn, and performs weaving while inserting a multifilament having a total fineness that is 80% or greater of the total fineness of the ground yarn into the selvage weave portion as a selvage-tightening yarn.

    摘要： The reinforcing carbon fibre base material of the present invention has metal wire arranged within the interior of the reinforcing carbon fibre base material and the volume fraction of the metal wire is no more than 4% of the reinforcing fibre, so FRPs of various shapes can be produced in the form of large-size structures or integrally formed therewith and, moreover, it is possible to detect the state of strain generated in the structures or FRPs accurately.
    With regard to the laminate and detection method of the present invention, by arranging metal wire in the reinforcing carbon fibre base material interior at a volume fraction of no more than 4% and, moreover, by layup said base material in such a way that the insertion positions of the metal wire are mutually different, the number of plies and lamination direction in the laminate, which cannot be detected by ordinary non-destructive inspection methods, can be detected simply and non-destructively.
    The reinforcing carbon fibre base material, laminate and detection method of the present invention are preferably employed for FRP-made structures and, in particular, in the repair and reinforcement of concrete structures.

    摘要： In conventional weaving methods, the tension of warp yarn at the sides in the width direction is insufficient during weaving, resulting in a difference in the crimp ratio between the center in the width direction and the sides in the width direction of the fabric. The difference in the crimp ratio has caused unevenness in a woven fabric in the width direction. As a solution, the present invention uses additional yarn having a boiling-water shrinkage rate less than that of the base yarn, thereby suppressing shrinkage at the sides in the width direction of the fabric and thus reducing the difference in the crimp ratio between the center in the width direction of the fabric and the sides in the width direction. This enables the production of a fabric for airbags with high uniformity in the width direction.
