Zusammenfassung:	A press forming method according to the novel 3D hybrid technology of the present invention comprises a metallic sheet and a fiber-reinforced polymer phase laminated on the metallic sheet. The metallic sheet utilizes a multilayer material in which a guide structure that determines at least one of a flow rate and a flow direction of the fiber-reinforced polymer phase molten by at least one of heating and pressing is pre-processed. Using this, forming is performed through a step of providing a multilayer material comprising a metallic sheet and a fiber-reinforced polymer phase and a step of applying at least one of heat and pressure to the multilayer material to melt the fiber-reinforced polymer phase. The multilayer material according to the present invention can simplify the forming process while having light weight and improved physical properties. In particular, according to the press forming method of the present invention, the formation of various design structures including complex surface structures can be achieved with a high degree of completion only with a single forming process by using the multilayer material in which the pre-processed guide structure is formed in advance. 본 발명의 새로운 3D 하이브리드 기술에 따른 프레스 성형 방법은 금속 시트, 금속 시트상에 적층된 섬유 강화 폴리머 페이즈를 포함하고, 금속 시트는 가열 및 가압 중 적어도 하나에 의하여 용융된 상기 섬유 강화 폴리머 페이즈의 유량 및 유동 방향 중 적어도 하나를 결정하는 가이드 구조가 사전 가공된 다중층 재료를 이용한다. 이를 이용해, 금속 시트(metallic sheet) 및 섬유 강화 폴리머 페이즈 (fiber-reinforced polymer phase)를 포함하는 다중층 재료를 제공하는 단계 및 다중층 재료에 대해 열 및 압력 중 적어도 하나를 인가하여 상기 섬유 강화 폴리머 페이즈를 용융시키는 단계를 거쳐 성형을 수행한다. 본 발명에 따른 다중층 재료는 경량화와 향상된 물성을 갖는 동시에 성형 공정을 단순화할 수 있으며, 특히, 본 발명에 따른 프레스 성형 방법에 의하면 이러한 사전 가공된 가이드 구조가 미리 형성된 다중층 재료를 이용함으로써 복잡한 표면 구조를 포함하는 다양한 설계 구조의 형성을 단일 성형 공정만으로 완성도 높게 달성할 수 있게 된다.
