Title (EN) PREPREG FOLDING AND FORMING APPARATUS AND FORMING METHOD THEREOF
(FR) APPAREIL DE MISE À PLAT ET DE FORMAGE DE PRÉ-IMPRÉGNÉS ET PROCÉDÉ DE FORMAGE DES PRÉ-IMPRÉGNÉS
(KO) 프리프레그 절곡 성형장치 및 그 성형방법
Abstract:
(EN) A prepreg folding and forming apparatus according to the present invention comprises: a vacuum chamber having an internal space under vacuum; an expansion unit which is arranged in the vacuum chamber, having an upper surface on which the prepreg is disposed, and which expands by the vacuum pressure in the vacuum chamber; a heating unit arranged in the vacuum chamber to heat the prepreg; a mandrel disposed on a portion of the upper surface of the prepreg; a first press unit brought into contact with the mandrel to press the mandrel; and a second press unit which presses the other portion of the upper surface of the prepreg and the expansion unit at the same time. The disclosed prepreg folding and forming apparatus can easily fold and form a plurality of prepregs which are stacked into a thick layer, and which can transfer sufficient pressure to the corner part of the mandrel by the pressure applied to the upper and lower surfaces of the prepreg, thereby preventing the prepreg from becoming wrinkled.
(FR) La présente invention porte sur un appareil de mise à plat et de formage de pré-imprégnés, qui comprend : une chambre à vide comportant un espace interne sous vide ; une unité d'expansion qui est disposée dans la chambre à vide, comportant une surface supérieure sur laquelle est disposée le pré-imprégné et qui subit une expansion par la pression négative dans la chambre à vide ; une unité de chauffage disposée dans la chambre à vide pour chauffer le pré-imprégné ; un mandrin disposé sur une partie de la surface supérieure du pré-imprégné ; une première unité de presse amenée en contact avec le mandrin pour presser le mandrin ; et une deuxième unité de presse qui presse l'autre partie de la surface supérieure du pré-imprégné et l'unité d'expansion en même temps. L'appareil de mise à plat et de formage de pré-imprégnés selon l'invention peut facilement mettre à plat et former une pluralité de pré-imprégnés qui sont empilés sous la forme d'une couche épaisse, et qui peuvent transférer une pression suffisante à la partie de coin du mandrin par la pression appliquée sur les surfaces supérieure et inférieure du pré-imprégné, empêcher ainsi le pré-imprégné de se rider.
(KO) 본 발명에 따른 프리프레그 절곡 성형장치는, 내부의 공간에 진공을 형성할 수 있는 진공챔버; 상기 진공챔버의 내부에 구비되며, 프리프레그가 상부에 놓이되 상기 진공챔버내의 진공압에 의해 팽창되는 팽창부; 상기 진공챔버의 내부에 구비되며, 상기 프리프레그를 가열하는 가열부; 상기 프리프레그의 상면 일측에 적재되는 맨드릴; 상기 맨드릴의 상면에 접촉되어 상기 맨드릴을 가압하는 제1가압부; 및 상기 프리프레그의 상면 타측과 상기 팽창부를 동시에 가압하는 제2가압부를 포함할 수 있다. 개시된 프리프레그 절곡 성형장치는, 복수개의 프리프레그가 두껍게 적층되더라도 용이하게 절곡성형할 수 있으며, 상기 프리프레그의 상, 하면에 인가되는 압력에 의해 맨드릴의 코너 부위에도 충분한 압력을 전달할 수 있어 주름 등이 발생되지 않는 장점이 있다.
