PURPOSE:To reveal effectively tensile strength and the modulus of elasticity which are possessed by a reinforcing fiber, by a method wherein after infiltration of resin into gauze fabrics, the resin is solidified under a state where tension is applied to the fabrics in the direction of weft and the tension is made into such strength that a bend degree of the weft of a netlike molded material becomes a specific value. CONSTITUTION:At the time of manufacturing of a netlike molded material comprised by fixing gauze fabrics with resin, after the resin is infiltrated into the gauze fabrics, the resin is solidified under a state where tension is applied to the fabrics in the direction of weft. Then the tension is made into such strength that a bend degree Cf of the weft of the netlike molded material to be defined by a formula I becomes less than 0.03. In the formula I, Lf is a mean distance between the wefts 1, 2 adjoining to each other, Df is a mean distance between the one top 12 of a wave form of the center line of the weft 3 and a line 15 obtained by connecting the two tops 13, 14 adjoining to the top 12. With this construction, strength and the modulus of elasticity which are possessed by a reinforced fiber in the direction of the weft are displayed effectively and loadings of the reinforced fiber can be reduced. |
