碩士 === 中華科技大學 === 飛機系統工程研究所在職專班 === 100 === ABSTRACT
Materials industry has become more important as the progress of technology. Composite materials are widely applied in high-tech products nowadays. However, the panels with the sandwich structure of composite materials would be destroyed by the external loads or strikes. The purpose of this study is to explore whether composite materials used as materials of repairing structure would recover the original strength. This article discusses its impact behavior of composite glass fiber sandwich structure and structure performance after repair, design using high density styrofoam core material mixed with epoxy resin and glass fiber made from different types of composite sandwich structures test piece, exploring the bending resistance of composite sandwich structure and ability to resist pressure and tensile strength. The experiment used a self design shocks equipment to simulate energy impacts with different levels of damage energy caused by different impacts angle and mass of weight. On the other hand, the impact damaged patch characteristics, and performance analysis of bending strength of composite sandwich structures will be discussed. The results indicated repaired test pieces enhanced the bending strength from 0.01 Mpa to 0.06 Mpa. It is suggested that repairing can enhanced the strength of material to the original strength and even better than the original one. The study implicated the repair of composite materials of structure by using glass fibers would cause the economic benefits in materials industry.
