The effects of non-stoichiometric curing on the dynamic compressive properties of bisphenol A-type epoxy resins were investigated experimentally to take into consideration the relation between mechanical properties and network structures in the epoxy resin. The yield stresses were found to be approximately linear to the strain rate regardless of crosslinking densities. Stress after yielding was clarified to rapidly reduce in epoxy resins with lower crosslinking densities and for higher strain rates.
