Abstract

용융한 열가소성 수지중에 연속한 보강용 섬유로빙을 도입하여 용융한 수지에 섬유를 함침시킨후, 인발장치를 사용하여 노즐로 과잉량의 수지를 짜넣기 하면서, 연속적으로 인발하는 공정과 이 공정에 의해 얻어지 스트랜드를 롤로 리본상으로 압압하는 공정, 더욱 압압된 스트랜드를 부형노즐로 통하여 영상을 정리하는 공정으로 되는 스트랜드상 섬유강화복합재료의 제조방법에 의해 깃털세움이 없고 섬유와 매트릭스의 밀착성이 우수한 장섬유강화 열가소성 수지 조성물을 제공한다.The continuous reinforcing fiber roving is introduced into the molten thermoplastic resin to impregnate the molten resin with fiber, and then the process of drawing continuously while squeezing excess resin through the nozzle using a drawing device. The method of producing a strand-like fiber-reinforced composite material, which involves pressing the obtained strand into a ribbon with a roll and arranging the image through the pressed nozzle with a pressed nozzle, has no feathering and excellent adhesion between the fiber and the matrix. Provided is a long fiber reinforced thermoplastic resin composition.

Claims (2)

용융한 열가소성 수지중에 연속한 보강용 섬유로빙을 도입하여 용융한 수지에 섬유를 함침시킨후, 인발장치를 사용하여 노즐로 과잉량의 수지를 짜넣기 하면서 연속적으로 인발하는 공정과, 이 공정에 의해 얻어지 스트랜드를 롤로 리본상으로 압압하는 공정, 더욱 압압된 스트랜드를 부형노즐로 통해 형상을 정리하는 공정으로 되는 스트랜드상섬유 강화복합재료의 제조방법.The continuous reinforcing fiber roving is introduced into the molten thermoplastic resin to impregnate the molten resin with the fibers, and then continuously drawn out while squeezing excess resin through the nozzle using a drawing device. A method for producing a strand-like fiber reinforced composite material, which comprises a step of pressing a resultant strand into a ribbon with a roll and a step of arranging the shape of the pressed strand through a shaping nozzle. 스트랜드를 롤로써 압압하는 공정에 있어서, 롤에 의한 압압이 다음의 식을 만족하는 범위로 행해지는 청구항 1기재의 스트랜드상섬유 강화복합재료의 제조방법.A method for producing a strand-like fiber-reinforced composite material according to claim 1, wherein in the step of pressing the strand with a roll, the pressing by the roll is performed in a range satisfying the following equation. b/a+2∼10b / a + 2 to 10 (다만, a는 크로스 헤드 다이를 나온 스트랜드직경(㎝), b는 압압된 리본상의 스트랜드의 횡폭(㎝)이다.)(However, a is the diameter of the strand out of the crosshead die (cm) and b is the width of the strand on the pressed ribbon (cm).) ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
