Zusammenfassung:	A fiber-reinforced composite material having a uniform surface is provided. The fiber-reinforced composite material comprises a non-flexible laminate including non-crimp fabric (NCF) sheets, at least one woven fabric sheet, and a non-woven fabric sheet disposed between the non-flexible laminate and the at least one woven fabric sheet. In the non-flexible laminate, at least one of the top and bottom layers is composed of one of the NCF sheets. The non-woven fabric sheet can improve surface uniformity of the fiber-reinforced composite material. 표면이 균일한 섬유보강 복합재료가 제공된다. 상기 섬유보강 복합재료는 NCF(non-crimp fabric) 시트들을 포함하는 비굴곡 적층체, 적어도 하나의 직조직물 시트 및 상기 비굴곡 적층체와 상기 적어도 하나의 직조직물 시트의 사이에 배치된 부직포 시트를 포함한다. 상기 비굴곡 적층체는 최상층과 최하층 중 적어도 하나의 층이 상기 NCF 시트들 중 하나로 구성된다. 상기 부직포 시트는 상기 섬유보강 복합재료의 표면 균일도를 향상시킬 수 있다.
