由奈米碳管、環氧樹脂與玻璃纖維組成的可程式化電控相轉變之高強度複合材料。可藉由加入奈米碳管以控制在玻璃轉換溫度時的吸收能量能力,藉由施加電壓將剛性複合材料變更為阻尼器與橡膠,達到快速吸震效果。並在加入玻璃纖維作為強化材料後,測試其阻尼特性以及玻璃轉換溫度改變。阻尼係數經量測為0.1,並可在約6秒內達到最大吸震能力。本文探討加入奈米碳管後,環氧樹脂與奈米碳管間的介面效應,並藉由實際模擬測試探討實際應用方向。人造衛星及太陽能板因機械構造產生的自然震動或是飛機與風力發電葉片因亂流與風阻產生的間歇性震動等均可使用此複合才達到快速吸震。亦可應用於房屋與橋梁之防震,藉由此材料破壞共振頻率,降低損失與意外發生機率。
Composites made from fibers and epoxy display a low viscous drag and are barely used as mechanical damper at room temperature. Incorporation of carbon nanotubes into epoxy promotes interfaces that govern damping mechanism in the vicinity of glass transition temperature. Damping character remains unchanged as glass fibers are also present in composites and damping coefficient is measured to be 0.1.
