摘要
研究了适用于RTM工艺的单组分耐高温环氧树脂的结构、性能和形态。红外光谱(FTIR)和核磁共振(1HNMR)表明MERICAN 3768和CYCOM 890两种单组分耐高温环氧树脂具有相同的结构组成。MERICAN 3768环氧树脂粘度低,在80℃放置12 h后,粘度从240 mPa·s增加为300 mPa·s,具有较长的工艺适用期,工艺性能可满足RTM工艺的要求。热重分析(TGA)和动态热机械分析(DMA)研究表明MERICAN 3768与CYCOM 890树脂的耐热性相近,MERICAN 3768树脂浇注体的力学性能与CYCOM 890相当。
The structures,properties and fracture image of one-component high-temperature epoxy resin suitable for RTM process were studied.FTIR and 1H NMR shows that MERICAN 3768 and CYCOM 890 have similar structural components.Viscosity of MERICAN 3768 is 240 mPa·s at 80℃and is increased to 300 mPa·s after 12 h at 80℃,which meets the requirements of RTM process.Thermal stability of MERICAN 3768 is similar to that of CYCOM 890 from thermogravimetric analysis(TGA)and dynamic mechanical analysis(DMA)analysis.Mechanical properties of MERICAN 3768 are similar to those of CYCOM 890.
