The present invention provides a FRP sound barrier comprising a core material and a skin material made of FRP located on both sides of the core material, the panel having a weight per unit area in the range of 10 to 60 kg / m 2 , and a manufacturing method thereof. do. This soundproof wall is lightweight, has excellent sound insulation performance, and does not corrode because it is made of FRP. In addition, the degree of freedom of design is high in terms of soundproofing performance, design, and shape, and a desired soundproof wall is easily formed. In addition, since the specific strength is high, the body having the required strength and weight can be greatly reduced, thereby facilitating the construction, shortening the construction period, and reducing the construction cost. |
