description Systems and methods are provided for applying lengthwise curvature to composite parts. One embodiment is a method that includes fabricating a preform for a curved pultruded gap filler by continuously: heating fiber reinforced material to a sticking point temperature for a constituent material within the fiber reinforced material, and feeding the fiber reinforced material through a die that exhibits a curvature through which the fiber reinforced material travels while the fiber reinforced material is heated to the sticking point temperature, the die forming the fiber reinforced material into a preform for a gap filler. Fabricating the curved pultruded preform further includes varying path lengths of fibers within the preform as the preform passes through the die, and pulling the preform out of the die. 복합 부품에 길이 방향 곡률을 적용하기 위한 시스템 및 방법이 제공된다. 한 실시 예는 연속적으로 휜 인발 성형 갭 필러(a curved pultruded gap filler)를 위한 프리폼(a preform)를 가공하는 것: 섬유 보강 재료(fiber reinforced material) 내의 구성 물질에 대한 고정 점 온도(a sticking point temperature)까지 섬유 보강 재료 가열, 및 섬유 보강 재료가 고정 점 온도(a sticking ping temperature)로 가열되는 동안, 섬유 보강 소재가 이동하는 곡률을 보이는 다이(a die)를 통해 섬유 보강 재료를 공급하는 것, 갭 필러를 위해 프리폼 내로 섬유 보강 재료를 성형하는 다이를 포함하는 방법이다. 휜 인발 성형 프리폼을 가공하는 것은 프리폼이 다이를 통해서 통과하는 것과 같이, 프리폼 내 섬유의 가변 경로 길이, 및 프리폼을 다이 밖으로 당기는 것을 추가로 포함한다.
