本計畫將利用兩年的時間，以實驗的方法針對同時添加碳奈米管及石墨烯微片於環氧樹脂基材之複合材料靜態及疲勞性質進行研究。計畫的目的在於探討同時添加碳奈米管及石墨烯兩種加強材與只使用其中一種加強材對於以環氧樹脂為基材之複合材料靜態及疲勞性質影響的比較，並討論其加強機制的異同。除此之外，研究也將尋求兩種碳加強材的配置比例，使得此類奈米複合材料具有最佳的靜態及疲勞性質；並探討其加強機制。研究中所探討的靜態及疲勞性質將以靜態拉伸實驗、基本疲勞實驗、破裂韌性測定實驗及疲勞裂縫成長實驗來評估。計畫的第一年將研究添加不同碳加強材含量對只添加一種碳加強材的奈米複合材料靜態及疲勞性質之影響，並確定最佳的碳加強材含量。第二年將以第一年的最佳碳加強材含量為基礎，研究同時添加兩種碳加強材對此類奈米複合材料靜態及疲勞性質之影響，並探討兩種碳加強材配置比例對其機械性質的影響。計畫中也將針對所使用的各類型奈米複合材料試片進行基本的物理及化學性質檢測，以瞭解所添加碳加強材種類的數目、含量及配置比例對其物理化學性質的影響。這些檢測包括：導電性質、熱機械性質、吸濕性質、黏彈性質、官能基及碳加強材分布檢測。在所有靜態及疲勞性質相關實驗完成後，也將對試片斷面做一檢視，以瞭解所添加碳加強材種類的數目、含量及配置比例對環氧樹脂基材機械性質加強機制的影響。"The two-year project will investigate experimentally the static and fatigue properties of the epoxy-based composites with the collective reinforcement of carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs). The purpose of this project is to study the synergistic effect of these two employed carbon fillers on the static and fatigue properties of the studied composites and to make a comparison on the reinforcement mechanisms between the composites with different fillers. The optimum allocation ratio between the two fillers will also be obtained experimentally. In the project, the static and fatigue properties of the nano-composites will be evaluated using the statically tensile tests, basic fatigue tests, measurement of fracture toughness, and fatigue crack growth tests. In the first year, the effect of the employed contents of the carbon fillers on the nano-composites with single carbon filler on the static and fatigue properties will be studied, and the optimum contents of the fillers will also be determined experimentally. According to the optimum contents of fillers obtained in the first year, the synergistic influence of the employment of two carbon fillers on the static and fatigue behaviors of the epoxy-based composites will be investigated in the second year. The effect of the allocation ratios between two studied fillers on the mechanical properties of the CNT/graphene/epoxy composites will also be studied. The fundamental physical and chemical properties of the various utilized nano-composite specimens will be examined to study the effects of types of employed carbon fillers, contents of fillers, and fractional ratios between the two fillers on the physical/chemical properties. These examined items include electrical property, thermos-mechanical property, moisture absorption ability, viscoelastic property, developed functional groups, and dispersion of fillers. After the static and fatigue tests, the fracture surfaces of the studied nano-composite specimens will be observed to understand the influences of types of employed carbon fillers, contents of fillers, and fractional ratios between the two fillers on the reinforcement mechanism of the employed carbon fillers on the epoxy matrix."
