Abstract
Based on the synthetic investigation of the mechanical properties,damping performance and high temperature resistant performance of AFLAS fluorine rubber,a new kind of viscoelastic damping material ingredient is presented,which can co-cure with carbon fiber/bismaleimides resin prepreg (T700/QY260)at 260℃ high temperature.The viscoelastic damping material is dissolved in tetrahydrofuran dissolvant to prepare the viscoelastic material solution.By using the double-sided brush coating process and autoclave process,the embedded high-temperature co-curing high damping composite specimens are manufactured.The free vibration attenuation experiments of these specimens are performed to measure the relative damping coefficients under the conditions of normal temperature and after 230℃*96 h and 260℃*96 h aging treatments.The relation between the damping coefficients and the damping material thickness after the aging treatment at different temperatures is obtained.The results verify that the embedded co-cured composite damping structure has excellent ultra-high temperature resistance property and the stable damping performance.关键词
