CFRP Prepreg 적층조건과 금형 마찰계수를 고려한 Double-dome 형상 성형해석 연구 = A study on the forming analysis of double-dome model considering CFRP prepreg laminate condition and coefficient of friction

다국어 초록 (Multilingual Abstract)

Recently, lightweight material is attracting attention as a solution to the problem of fuel efficiency and increasing the need for development. CFRP has been attracting attention as lightweight materials for automobile because it has a high specific stiffness and specific strength compared to steel material. CFRP have a wide range of mechanical properties depending on the laminate condition. In this paper, study on the forming analysis of double-dome model was performed considering CFRP prepreg laminate condition and coefficient of friction. After forming analysis, the result has compared with wrinkling area and vertical strain of fiber to the laminated condition. And then compared with inflow of blank to the laminate condition. Through this paper, we propose the forming analysis methods of CFRP material.
