Abstract
In this paper, under the effect of MD1041 cashew oil modified phenolic amine curing agent for epoxy resin, it successfully prepared polyurethane flexible resin modified epoxy resin composite materials by using polyurethane modified epoxy resin reinforced flexible resin. Modified composite material of the new preparation is characteristed by the method of the mechanical performance test, Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC). The results show that the flexible resin has a strong effect on the toughness of modified epoxy resin composite materials. When the mass ratio of the flexible resin account for 5.9%,comprehensive mechanical properties of the modified composites is at the premium; when the mass ratio of flexible resin account for 3.1%, the thermal stability of the epoxy resin modified with flexible resin is at the best.
