中文摘要 複合材料為現代常用的材料,其中纖維疊層板複合材料為應用最廣,因其纖維方向的特性,可以改變其排列方式來因應多種狀況達到加強效果,而奈米碳管為目前新興的補強材料,由於它具有優秀的機械性質,如高強度、高韌性、高硬度等等之特性,所以很適合作為補強材料。本文透過複合材料的加勁方式來結合碳纖維、樹脂及奈米碳管,並加入纖維方向之特性與各個材料之市場價格,想藉著ANSYS裡的最佳化模組,來找出最適合的各個材料的體積比與角度配置方式,最後再與傳統的純碳纖疊層板相較其花費與重量改善狀況。
英文摘要 Composite materials are common materials using in engineering and the fiber composite laminate is widely used. With various fiber arrangement, the strength of material can be enhanced. Since the carbon nanotube has mechanical properties with high strength and high stiffness, it is appropriately used as reinforcement material. In this study, carbon fiber, epoxy and carbon nanotube are combined by Rule of Mixture and Halpin-Tsai equation, and the fiber direction and price of materials are also considered. The optimum arrangement of fiber direction and material volume fraction are calculated by ANSYS. Finally, the optimum results of cost and weight are compared with typical carbon fiber laminate.
