A new type of epoxy resin, which contained cyanate functional group in the main chain, was synthesized. The synthesized resin was characterized by FT-IR spectroscopy. New epoxy resin was then cured by amine curing agent. And, the effect of cyanate group to the epoxy resin on the cure behavior, thermal, and mechanical properties was investigated. The cure behavior of the epoxy resin was evaluated from the differential scanning calorimetry. The thermal stability of the cured specimen was monitored by thermogravimetric analysis. Also, the critical stress intensity factor (KIC) for mechanical properties was measured by universal testing machine. |
