Effect of Montmorillonite on Microstructure and Mechanical Properties of Epoxy Resin
摘要
Abstract
The exfoliated epoxy resin/MMT nanocomposites were prepared by pre-exfoliated method, and the effect of montmorillonite on microstructure and mechanical properties of epoxy resin were studied by XRD, SEM and DMA. Experimental results showed that it’ s good for preparing exfoliated epoxy resin/MMT nanocomposites to pre-exfoliate montmorillonite before curing epoxy resin E53. Due to the addition of montmorillonite, the Tg of epoxy resin/MMT nanocomposites was about 5 ℃ ~8 ℃ higher than that of the epoxy resin. The storage modulus and stiffness of the ep-oxy resin increased with the increasing of Tg , and lower β transformation temperature made the best low temperature toughness. So exfoliated inorganic nanosheets can effectively prevent cracks along the exhibition, and play the role of reinforcing and toughening in epoxy resin/MMT nanocomposites.关键词
