Abstract

본 발명은 탄소섬유와 열경화성 수지로 이루어진 굴곡탄성률이 향상된 판상 스프링의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a plate-like spring with improved elastic modulus of elasticity consisting of carbon fiber and thermosetting resin.

본 발명은 탄소섬유를 열경화성 수지에 함침하여 탄소섬유 예비쉬트로 만든후, 이 예비쉬트를 배향각을 주면서 적층한 다음, 진공성형하는 것을 특징으로 한다. 적절한 배향각은 20~30도이며, 탄소섬유 예비쉬트의 탄소섬유:열경화성 수지의 조성비가 50~70중량%이고, 그 적층수는 4이상이다.The present invention is characterized in that the carbon fiber is impregnated with a thermosetting resin to form a carbon fiber preliminary sheet, and then the preliminary sheet is laminated while giving an orientation angle, followed by vacuum forming. A suitable orientation angle is 20-30 degree | times, the composition ratio of the carbon fiber: thermosetting resin of a carbon fiber preliminary sheet is 50 to 70 weight%, and the number of lamination | stackings is four or more.

본 발명에 의한 판상 스프링은 가볍고 내구성이 좋을 뿐만 아니라, 굴곡탄성률이 우수하다.The plate spring according to the present invention is not only light and durable, but also has excellent flexural modulus.
