Description

섬유강화 플라스틱 재료로 만든 성형제품
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 성형시키기 위해 준비한 섬유강화 플라스틱재료의 형상시이트의 등각투영도,
제2도는 제1도의 시이트가 두 부분으로 구성된 성형틀안에서 성형되는 과정의 측면선도,
제5도는 성형틀로부터 떼어낸 성형제품의 등각투영도.

Claims (8)

  1. 길이가 약 7-50mm이고 탄성계수가 높은 강화섬유 20-70중량%가 분산되어 있는 압축된 열가소성 재료의 시이트를 팽창시켜서 강화섬유내의 응력을 완화시키기 위해 상기 시이트를 예열시키고 팽창된 시이트를 압축 성형틀내에 위치시킨 후, 부분적으로 다른 밀도를 갖는 예정된 형태의 성형품을 형성하도록 성형틀을 폐쇄시키는 과정을 포함하는 섬유강화 플라스틱의 제조방법.
  2. 제1항에 있어서, 성형틀의 최소한의 부분까지도 시이트로 완전히 조밀하게 채워지도록 시이트를 압착시키는 과정을 포함하는 제조방법.
  3. 제1항 또는 2항에 있어서, 성형과정동안 밀도가 더 큰 부분에 삽입물을 부착시키는 과정을 포함함을 특징으로 하는 제조방법.
  4. 제1항 내지 3항중 어느 한항에 있어서, 열가소성 재료가 최소한 30중량%의 유리섬유를 포함함을 특징으로 하는 제조방법.
  5. 제4항에 있어서, 열가소성 재료가 50중량%의 유리섬유를 포함함을 특징으로 하는 제조방법.
  6. 제1항 내지 5항중 어느 한항에 있어서, 시이트는 돌이상의 구성이 다른 플라스틱재료층이 성형과정 동안에 서로 적층을 이루어 형성된 것임을 특징으로 하는 제조방법.
  7. 제6항에 있어서, 셋이상의 층이 결합되어 있을 때, 외부층은 내부층이나 중간층보다 섬유성분을 중량비로 더 적게 포함함을 특징으로 하는 제조방법.
  8. 제1항 내지 7항중 어느 한항의 방법에 의하여 제조된 섬유강화 플라스틱을 재료로 한 성형제품.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
