摘要

光纖光柵為通訊工程中常用之通訊元件，經過特殊加工後製成感測元件，目前已普遍應用於土木工程、航太工程等領域為監測量測之工具，光纖光柵感測器結合了許多的優點，如體積小、徑細質輕、不受電磁波干擾、高傳輸性、耐腐蝕、耐高溫、易於埋入結構物中及可作為分佈式多工監測網路等，適用於結構物的應變與溫度監測。
複合材料FRP現今已廣泛運用於船舶遊艇、航太載具、風電葉片等結構物中，但隨著結構大型化之趨勢，對於結構安全及品質的要求，所以對於結構之監測預警與診斷技術日漸重要，且由於光纖感測器容易內埋之優點，可以在複合材料結構製作過程中預先內埋於結構物中，以便於結構物成型後監測結構內部狀況。
本研究主要在於利用光纖光柵感測器應用於VARTM製程中，將光纖光柵感測器內埋於纖維積層中，監測樹脂灌注時之流動波前，並探討光纖光柵感測器波長變化與樹脂流動波前之關係，且實際應用於厚積層板之灌注實驗，監測纖維積層內部之樹脂流動波前，再與模擬軟體分析結果進行探討，驗證光纖光柵感測器監測樹脂流動波前之適用性。

The optic fiber is the commonly used in communication, after special processing it can be made a sensing part. At present, fiber optic sensors are applied generally in civil engineering and aeronautics, astronautics engineering for monitoring. The fiber grating sensor unified many merits, for example, the volume is small, the diameter thin and mass is light, not electromagnetic wave disturbance, High transmission, Anti-corrosive, thermostable, easy to embedded in the structure and establish quasi-distributional multiplex monitor network, It’s suitable in the structure strain and the temperature monitoring.
Nowadays, composite FRP usually has used to the yacht, aerospace vehicle, windmill rotor structures etc., but tendency of along with the structure of large scale, regarding structure security and quality request, Therefore forewarn monitor of regarding the structure and diagnoses the technology to be important day after day, Because the fiber optical sensor has easy to embedded in structure. So it’s can embed fiber optic sensor in composite structure manufacture in the structure, After the structure formation , advantageously monitor the structure interior condition.
This research mainly lies is used fiber grating sensor that applied to Vacuum Assisted Resin Transfer Molding (VARTM) process, fiber grating sensor was embedded between the fabric layers to monitoring the resin flow in composite process, and discusses relations of the fiber grating wavelength change and the resin flow. Practical application resin flow of experiment in thick laminate. Monitoring internal resin flow front in thick laminate. Discussion on experiment result and simulation software analysis result. Serviceability of the confirmation fiber grating sensor monitor resin flow front.
