| dc.description.abstract | 複合材料因為輕巧與堅韌等特性，已廣泛應用於許多產業，如航太工業、汽車產業、造船工業以及風力發電等。膠合法為連結複合材料的主要方法，膠合法擁有降低應力集中、輕量化等優點，但膠合區域為整體結構最為脆弱之處，許多學者也致力於如何提升接點的極限負載，近年來以改變膠合接點的外型(如試片導角、波浪形試片等)成為研究方向之一。本研究設計出非平表面幾何之複合材料單搭接點，應用複合材料Seemann真空灌注製程(Seemann Composite Resin Infusion Molding Process, SCRIMP)，在乾毯纖維下方埋入具有硬度的鐵線，鐵線可以在真空製程中被大氣壓力形成非平坦表面，注入樹脂後熱固化形成一具有非平坦表面幾何的複合材料，並參照美國材料試驗學會(American Society for Testing and Materials, ASTM)所制定的複合材料膠合試片測試標準ASTM D5868-01製作單搭接點膠合試片。本研究不僅透過大部分文獻作者使用的實驗與模擬印證方法，並且使用高速攝影機觀察裂紋生長情形。本研究改變的參數有：加強材位置、結構膠性質、環境因素、加強材直徑以及結構膠厚度，並且以一般傳統平坦接點為對照組，實驗結果為非平表面試片能有效提升極限負載，並探討提升極限負載之原因，尋找出最適合的非平表面幾何，實驗結果、模擬分析與裂紋傳遞之間有著良好的一致性。本研究提出之非平表面幾何製作工藝，不需額外訂製新模具，因其方便性、較佳的極限負載表現，有利於複合材料應用在相關產業中的可行性。 | zh_TW |
| dc.description.abstract | Composite materials have been widely applied in many industries, such as aerospace, automotive, shipbuilding and wind power generation due to their high strength to weight ratio properties. Adhesively bonded joint is main method for connecting composite materials; whilst this has the advantage of minimizing stress concentrations and being lightweight, the bonding area is the weakest link of the overall structure. Many researchers have investigated the means of enhancing the load carrying capacity of the bonded joint such as changing the surface geometry (e.g. wavy, taper, fillet) to decrease stress concentration and improve the tensile load of the bonded area. In this work, the reinforced materials were embedded in the glass-fiber lamina and formed a non-flat geometry under the Seemann Composite Resin Infused Molding Process (SCRIMP). The specimens were fabricated by following the ASTM D5868-01 standard. Specimens were investigated experimentally, numerically. Crack propagation under tensile test was observed using high speed camera imagery to help explaining the mechanism of improving the joint load capabilities. Parametric studies, involving changing the reinforcing material arrangement, the adhesive’s properties, ambient temperatures, the diameter of the reinforcing materials and the thickness of the adhesive were investigated. The experimental, simulation and crack propagation results are all in good agreement. This research, commonplace in the composite material fabrication general process, benefits the fabrication of non-flat surface structure without requiring special molds for determining better load performance data. Overall, it greatly advances the feasibility of the use of composite materials in multiple related industries. | en |
