Method of manufacturing three-dimensional textile reinforcement member and method of constructing textile-reinforced concrete structure using the same

A method of manufacturing a three-dimensional textile reinforcement material, the method comprising steps of:

• (a) forming a first two-dimensional grid by impregnating a two-dimensionally woven textile grid in a thermosetting resin and heat curing the two-dimensionally woven textile grid, the first two-dimensional grid including a first two-dimensional grid warp and weft;
• (b) forming a second two-dimensional grid by impregnating a two-dimensionally woven textile grid in a heated thermosetting resin and cool curing the two-dimensionally woven textile grid;
• (c) heat melting a bent position of the second two-dimensional grid;
• (d) bending the second two-dimensional grid at the bent position into a predetermined shape to form bent wefts;
• (e) cool curing the bent second two-dimensional grid;
• and
• (f) forming a three-dimensional textile reinforcement material by coupling the first two-dimensional grid and the bent second two-dimensional grid,
• wherein the second two-dimensional grid that is bent into a three-dimensional shape is inserted upward from a lower surface of the first two-dimensional grid so as to be primarily coupled therewith in order that the bent second two-dimensional grid is coupled with at least the one first two-dimensional grid so that the three-dimensional textile reinforcement material has a three-dimensional structure,
• wherein the bent second two-dimensional grid is inserted upward from the lower surface of the first two-dimensional grid, and the bent wefts on the second two-dimensional grid are disposed on both sides of the first two-dimensional grid warp,
• wherein, the first two-dimensional grid is reinforced by the bent second two-dimensional grid to perform bidirectional supporting.
