Recently, composites are used a wide variety of fields. Representative resin materials for the production of composite materials include thermosetting resins such as epoxy resins, polyester resins, and phenol resins, and thermoplastic resins include acrylic resins. The epoxy resin is widely used as a matrix of thermosetting prepreg because of excellent interfacial adhesion with carbon fiber. Composite materials with thermoplastic resin matrix are simple, excellent in processability and excellent in impact resistance. But they have limitations in aviation and automotive parts due to their low heat resistance. Therefore, it is necessary to develop a resin that can satisfy both high heat resistance, high strength, and impact resistance in order to be applied to aviation and automobile parts. In this study, functional materials such as nanosilica and poly ethersulfone (PES) were selected to give high heat resistance,high strength and impact resistance to thermosetting resins. |
