热氧老化对炭纤维/双马树脂复合材料力学性能的影响
Influence of thermal-oxidative aging on mechanical property of carbon fiber bismaleimide resin composites
摘要
Abstract
The experiment of thermal-oxidative aging on carbon fiber reinforced composite material at 150 ℃ and 210 ℃ was carried out to analyze weight loss,inter laminar shear properties,dynamic mechanical properties and infrared spectra of this composite at different aging temperature.The results show that early aging of the composite has mass loss quickly,while the inter laminar shear strength has been improved.With the increase of aging time,the mass loss rate at 150 ℃ gradually tends to stabilize,and the inter laminar shear strength increases slightly after fall first.There is only physical aging at 150 ℃ aging temperature.The mass loss rate still increase at the aging temperature 210 ℃,and physical aging and chemical aging occurs at the same time.The degradation of resin matrix oxidative result in performance of matrix and interface degenerate,making inter laminar shear strength continuously decline.关键词
