| dc.description.abstract | 隨著材料科學的演進，輕量化且兼具強度的材料逐漸被開發出來，其中纖維增強塑料FRP被廣泛使用在汽車，船舶和風力發電扇葉等行業，在材料結構完整性的監測上多半使用超音波掃描探傷或是在材料製作完成時敲擊聽音，然而這些方法在實際成品的監測應用上有其限制，將多壁奈米碳管添加至FRP使其產生導電性，用其導電性建立完整的破壞監測機制並實現多點監測為本研究之目的。
第一部份先比較在有無分散劑之情況下將多壁奈米碳管混入環氧樹脂A劑之分散效果，並發現只要透過適當製程亦可在無分散劑情況下做到相近效果之分散，並且可以減少後續抽去溶劑會產生之衍生問題。 第二部份則是比較不同真空管路佈管方式對試片成品之影響，並且說明如何佈置電極並得到形狀均勻且碳管分散均勻之多點監測試片。 第三部分則是將CNT GE試片進行直接拉伸，循環加載卸載與疲勞試驗，觀察拉伸試驗與疲勞試驗中各頻道的電壓變化，再將不同疲勞負載下的電壓變化相互比較，以及比較拉伸和疲勞試驗的電壓變化差異，進而分析不同破壞形式對電壓可能產生之影響。 | zh_TW |
| dc.description.abstract | With the evolution of materials science, lightweight and strength materials have been gradually developed. Among them, fiber reinforced plastic FRP is widely used in industries such as automobiles, ships and wind turbine blades, and most of them use ultrasonic waves in the monitoring of structural integrity of materials. Scanning flaw detection or tapping the sound when the material is finished. However, these methods have limitations in the actual application of the finished product. Add MWCNT to the FRP to make it conductive, and use its conductivity to establish a complete damage monitoring mechanism and realization of multi-point monitoring is the purpose of this study. The first part compares the dispersion of multi-walled carbon nanotubes mixed with epoxy resin A with add dispersant or not, and finds that similar effects can be dispersed without dispersing through proper process. And can reduce the problems that can be caused by solvent remove. The second part is to compare the effects of different vacuum pipeline arrange , and explain how to arrange the electrodes and get a multi-point monitoring speciman with uniform shape and uniform carbon tube dispersion. The third part is do tensile test, cyclic loading and unloading test and fatigue test, observe the voltage change of each channel in tensile test and fatigue test, compare the voltage changes under different fatigue loads, and compare the difference in voltage variation between tensile and fatigue tests to analyze the effect of different failure modes on the voltage variation. | en |
