| 제목 | Development of epoxy resin for VARTM to manufacturing large offshore structure |
| 초록 | One of the methods of manufacturing large offshore structures is the use of composite materials. In general, the VARTM method is used to manufacture large structures. The VARTM method consists of a mold on one side and a vacuum bag. Using the pressure difference between the inside of the mold and atmospheric pressure, the resin is quickly impregnated into the preform laminated inside the mold. In this way, the composite structure is formed. Various types of materials can be used for VARTM molding. Among them, the epoxy laminating system is formulated to manufacture high performance lightweight structures with glass, carbon, aramid and basalt reinforcements with or without post-curing. In this study, the synthesis of epoxy resins used for VARTM molding and their physical properties were evaluated. In addition, in order to improve impact resistance, functional additive materials were compounded and their properties were compared and evaluated. |
