摘要

材料的演進由早期追求高強度輕質量, 發展到具感應及反應功能的智慧型材料, 藉由埋於結構內之感測器偵測器偵測周圍環境如溫度應力應變, 並能作出適當反應, 保護結構免於受損, 或調整結構至最佳使用狀態. 本文以內埋光纖感測器之對稱交叉疊層複合材料為智慧型結構, 結合複合材料層板理論, 微觀力學分析及光彈理論, 探討干涉度量型光纖應變感測器埋在複材結構中之力學行為及量測表現, 訂定量測可靠度及準確度的評估準則, 並就光纖被覆材質與厚度對量測結果之影響進行分析.

The development of material is from the early high-strength, low-weight materials with sensing and acting performance, which detect enviornment such as temperature, stress, strain by the sensors embedded in the structure in order to protect the structure from damage or adjust the structure to the structure to the best performance. The present research discuss the symmetric cross-ply composite and combine the laminate theory, micromechanics analysis and photoelastic theory to analyze the mechanic behavior and measuring performance of the interferometric fiber optic sensor embedded in composites and set the evaluative principles of reliability and accracy. Then we can analyze the effect of viaration of material properties and thickness of coating.
