Analysis on rubber-modified Epoxy resin

Abstract

Analysis on rubber modified epoxy resin is presented. In rubber modified epoxy resin, rubber particles are contained in Epoxy matrix. Epoxy can be regarded as a brittle matrix material and does not undergo much nonlinear deformation. It has been seen in literature that Epoxy undergoes a considerable amount of nonlinear deformation when it is mixed with rubber. Such a material is called rubber modified Epoxy resin. It has also pointed out in literature that the primary cause of nonlinear deformation is the cavitations (fracture) of rubber particles which are embedded in Epoxy matrix. In this paper, a BE (boundary element) based homogenization method is applied to analyze the deformation of rubber-modified Epoxy resin.
