Development of Research on Toughening Epoxy Resin

Toughening epoxy is very important in the field of epoxy.Development of research on toughening epoxy resin are reviewed.Epoxy resin toughened by liquid crystal polymer(TLCP),interpenetrating polymer network (IPN) and nano-particles in recent years are introduced in detail.These methods can obviously improve the integrate performances of epoxy.The advantages,disadvantages and toughening mechanism are also explained.
