中文摘要 | 近年來,國內外致力研究複合材料之結構補強,目前在結構補強方面上,已有多種方法如纖維補強材料Fiber Reinforced Polymers (FRP),三明治結構補強方式,3D編織法等。關於基材(matrix material)之選用大多以環氧與酚醛樹酯為主。環氧樹脂與酚醛樹脂屬於有機高分子材料,在常溫溫度下接著強度甚強,但隨著溫度升高,物性急遽下降,耐溫性不佳,是眾所周知的缺陷。 有鑑於高分子材料耐溫性差之缺陷,本研究使用環氧酚醛樹脂交聯型高分子樹脂作為基材,並藉由填充短碳纖維(一維複合材料:環氧酚醛樹酯EP-1D)、纖維編織布(二維複合材料:環氧酚醛樹酯EP-2D)及鋼網結構(三維複合材料:環氧酚醛樹酯EP-3D)製備複合材料,提升複合材料高溫機械強度以擴展材料之使用範圍。研究過程,藉由實驗探討碳纖維、纖維編織布及金屬鋼網等不同結構型態複材在常溫(攝氏30度)、攝氏150度、攝氏250度、攝氏350度及攝氏450度等不同溫度之抗剪強度。實驗結果顯示3D補強複合材料有優異的耐高溫特性,具有應用於高溫環境下的潛力。 |
英文摘要 | In recent years, domestic and international researchers dedicated to the study on the structure of composite reinforcement. Currently, there are a variety of methods: fiber reinforced polymers (FRP), sandwich structural reinforcement mode, and 3D weaving method are applied in the structural reinforcement aspect. The choices of matrix material are mostly based on epoxy and phenolic resin. Epoxy and phenolic resin belong to the organic polymer resin material, therefore their adhesion are strongly affected by temperature whose adhesive properties dropped sharply with the increment of ambient temperature, which is the well known drawbacks. This study attempts to use epoxy phenol resin cross linked polymer resin as a substrate, and by using short carbon fiber (one-dimensional), fiber woven cloth (two-dimensional) and steel mesh (three-dimensional) as composite material structure to improve composite material’s mechanical property. By means of experimental process to study the shear stress for carbon fibers, fiber woven cloth and steel mesh at the room temperature, 150°C, 250°C, 350°C and 450°C, respectively. Experimental results show 3D reinforced composite materials have excellent temperature resistance. Therefore, 3D reinforced composite materials have the potential to be applied to high-temperature environments. |
