| Summary: | 碩士 === 大葉大學 === 工業工程與管理學系 === 105 === Carbon fiber composite material with light weight, high strength, high temperature, corrosion resistance and conductivity and other excellent features. So most of the aircraft used in the industry, steam locomotive industry, bicycle industry and medical and health industries. However, if the carbon fiber composite products to be lightweight and maintain the high-strength nature of the need for new materials research and development and manufacturing.
In this study, the carbon nanotubes in the nanometer powder and the graphene were used as reinforcing reinforcement in the carbon fiber composite material. First,0.5 wt%, 1.0 wt%, 1.5 wt%, 2.0 wt% %, 2.5 wt% of the nano-powder by weight of the carbon fiber composite material to test, to observe the bending strength and ultimate strength to find the best weight percentage. The experimental results show that when the addition of carbon nanotubes to 1.5wt% and graphene addition to 1.0%, the mechanical properties of the best.
(1: 5, 1: 3, 1: 1, 3: 1, 5: 1) were used to detect the mechanical properties by the preliminary study data. The experimental results show that when the ratio of carbon nanotubes to graphene is 1: 1, the ultimate strength and tensile strength can be improved.
