Microstructure and affecting factors of epoxy resin cured by electron beam radiation

  • Received Date: 20 Oct 2006

  • A scanning electron microscope (SEM) was used to observe the microstructures of cured samples after different cure time. The formation mechanism of microstructure was analyzed. The effects of molecular structure and molecular weight of epoxy resin, resin component, and radiation condition on the microstructure were also researched. The results show that the cure zone of epoxy resin consists of lamellae, and the resin molecular structure and weight have little effect on the cured microstructure. Under the electron beam radiation, epoxy resins with different structures or molecular weights all form prepolymer at first, then the prepolymer grows into network. With the radiation time increases, the network grows larger and the circular sheet forms finally. With the increasing of radiation dosage, the size of circular sheet increases. And there exists an optimum content of initiator, which makes the size of circular sheet reach the minimum.
