Zusammenfassung:The present invention relates to a method of manufacturing a wing for an unmanned aerial vehicle system and a blade for wind power generation. In order to manufacture a desired composite structure by performing a forming and curing process only once, the method of manufacturing lightweight wing and blade using a composite material of the present invention comprises: a step (S10) of coiling a carbon composite material tape (T) on a leading and trailing edge molds (M1, M2), and folding the carbon composite material tape (T) coiled on the leading and trailing edge molds (M1, M2) to manufacture a plurality of leading and trailing edge ribs (R1, R2) having a flange (F) and a web (W); a step (S20) of aligning the leading and trailing edge ribs (R1, R2) at predetermined intervals in accordance with the length of each of wings (B); a step (S30) of coupling each of spar molds (M3, M4) to a rear end of the leading edge rib (R1) and a front end of the trailing edge rib (R2), thereby attaching a composite material prepreg (T) to the rear end of the leading edge rib (R1) and the front end of the trailing edge rib (R2) to form spars (S1, S2); a step (S40) of bringing the spars (S1, S2) attached to the leading and trailing edge ribs (R1, R2) into contact with each other to integrate a wing and blade assembly comprised of the leading and trailing edge ribs (R1, R2) and a spar (S); a step (S50) of injecting the wing and blade assembly into a vacuum bag to form and cure the wing and blade assembly by a curing device such as an oven or the like; a step (S60) of separating the leading and trailing edge molds and the spar molds from the wing and blade assembly; and a step (S70) of attaching a separately manufactured leading edge skin to the wing and blade assembly from which the leading and trailing edge molds and the spar molds have been separated. 본 발명은 무인기용 날개나 풍력 발전용 블레이드를 제조하는 방법에 관한 것으로, 원하는 복합재 구조물을 단 한 번의 성형 경화 공정을 거쳐 제조할 수 있도록 앞,뒷전 몰드(M1,M2)에 카본 복합재 테이프(T)를 감고 접어서 플랜지(F)와 웹(W)을 갖는 복수의 앞전 및 뒷전 리브(R1,R2)를 제작하고(S10); 앞전 및 뒷전 리브(R1,R2)를 각각 날개(B)의 길이에 맞추어 정해진 간격으로 정렬하며(S20), 앞전 리브(R1)의 후단과 뒷전 리브(R2)의 선단에 각각 스파 몰드(M3,M4)를 결합하여 복합재 프리프레그(T)를 부착하여 스파(S1,S2)를 형성하고(S30), 앞,뒷전 리브(R1,R2)에 부착된 스파(S1,S2)를 맞대어 앞,뒷전 리브(R1,R2)와 스파(S)로 이루어진 날개 및 블레이드 조립체를 일체화하여(S40), 진공백에 투입하여 오븐 등과 같은 경화장비에서 성형 경화한 후(S50), 날개 및 블레이드 조립체에서 앞,뒷전 몰드와 스파 몰드를 분리하고(S60), 마지막으로 앞,뒷전 몰드와 스파 몰드가 분리된 날개 및 블레이드 조립체에 별도로 제작된 앞전 스킨을 부착(S70)하는 단계로 이루어진다.
