Shape memory epoxy resin has a good shape memory properties, mechanical properties and other properties are very good, so more and more eyes on the new materials, I hope this material can be obtained in the aerospace sufficient one, to meet the increasingly stringent requirement on the spatial structure of the material. In this paper, the properties of flexible epoxy epoxy resin system are studied by using the anhydride type curing agent flexible 3298 as the main body experiment.. For the research of flexible epoxy content influence on the performance of epoxy resin system, the experiment on the prepared samples were scanning electron microscope analysis, infrared spectrum analysis, detection of DMA, shape memory properties detection, tensile test, impact test, I hope the best formulation is obtained, high epoxy resin mechanical properties.
The research shows that the carboxyl group of the flexible epoxy group and the epoxy group of E-51 react with the ester bond.. Partial degree of crosslinking. While the content of the flexible epoxy in 30%-40%, the epoxy resin in the mechanical properties, the tensile strength of the maximum of 36.01MPa. Under this condition, the impact strength is 73.74 kj/m2.
