PROPERTY STUDIES OF HIGH-TEMPERATURE EPOXY RESIN FOR RTM

Abstract

Abstract: 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.

Key words: RTM process, one-component epoxy resin, thermal stability, mechanical properties
