PURPOSE:To provide a glass reinforcing material of FRP, which is hard to get slipping of the intersecting position of the threads, in which no thread cast- off occurs and which is hard to get the thread untied at FRP working. CONSTITUTION:The glass reinforcing material concerned is so constituted at the arrange synthetic fiber threads or metal thread 2, the elasticity of which is low and the restoring properties of which are weak, at the intersecting positions 3 of threads in the weaving of reinforcing material woven fabric (a) for FRP out of glass roving 1 and the like. |
