Study on microwave curing behavior and performance of epoxy/versamid 125

摘要

The curing rate of epoxy/Versamid 125 (V125) by heating curing,room-temperature curing and microwave curing was compared.It is founded that applying microwave technology could effectively improve the curing rate and the curing time is only 3-4minutes.140W microwave could cure the epoxy system in good condition,but 280W and 420W were easy to make the materials coking.The impact of diluent on mechnical properties of curing product were studied and it is showed that the impact strength increases and the impact ductility will be improved with the content of diluent increases,while the compressing strength,bending strength and tensile strength decrease.
