In the present invention, since a base material is formed by reinforcing both sides of a thermoplastic resin layer with reinforcing layers, flexural rigidity required is satisfied while reducing a weight of the entire base material, thereby preventing accidents that may occur due to an increase in weight. Particularly, in the present invention, the structural rigidity of the base material is reinforced through a glass mat forming the reinforcing layers to increase the formability and flexural rigidity of the base material, and the thermoplastic resin sheets are formed on both sides of the glass mat so that the glass mat can be directly attached without using an adhesive agent, and the formability and flexural rigidity can be further increased. In addition, since polyurethane foam is not used in the present invention, a problem such as dust is not generated when the polyurethane is formed into a sheet form so that a worker can safely work in a pleasant working environment.

    본 발명은 열가소성 수지층의 양쪽 면을 보강층으로 보강하여 기재를 구성하므로, 기재 전체의 중량을 줄이면서도 요구하는 굴곡 강도를 만족할 수 있게 하여 중량 증가로 발생할 수 있는 안전사고를 미리 방지할 수 있다. 특히, 본 발명은 보강층을 구성하는 글라스 매트를 통해 기재의 구조적 강성을 보강하여 기재의 성형성과 굴곡 강도를 높이고, 또한 글라스 매트의 양면에 각각 열가소성 수지 시트를 구성하여 별도로 접착제 등을 사용하지 않고서도 바로 부착할 수 있을 뿐만 아니라 성형성과 굴곡 강성을 더욱 높일 수 있다. 그리고, 본 발명은 폴리우레탄 폼을 이용하지 않으므로 폴리우레탄을 시트 형태로 제작할 때 생기는 문제, 예를 들어 분진 등이 생기지 않으므로 쾌적한 작업환경에서 작업자가 안전하게 작업할 수 있다.
