ABSTRACT:
At both ends of glass cloth comprising warp yarns consisting of a number of glass monofilaments and weft yarns consisting of a number of glass monofilaments, the weft yarns being cut at the ends of the glass cloth, glass monofilament-fixing portions are formed by fusing the ends of the weft yarns, by substituting a synthetic resin yarn for the warp yarn at the end of the glass cloth and melting the synthetic resin yarn or by attaching an adhesive tape to the ends of the glass cloth. The glass cloth having the glass monofilament-fixing portions at both ends thereof is advantageous in that no broken pieces of glass monofilament were formed when preparing prepreg or laminate using the glass cloth, and the laminate has excellent accuracy of thickness.
