Epoxy/amine reactive systems for composites materials and their thermomechanical properties

Abstract

In this chapter, epoxy/amines systems are studied during their synthesis and once they are synthesized. In the first part of this chapter, the different cross-linking mechanisms and their kinetics are presented. Then the evolution of the rheology of the reactive system, in particular the viscosity evolution of the reactive system with the progress of the conversion rate, is discussed. In the literature, different models are proposed to present this evolution. At the end of this part, some characteristics of different epoxy/amine systems, determined by different authors, have been recapitulated. In the second part, this chapter is interested in the thermomechanical behavior of epoxy/amines systems. In this part, effect of temperature on stress–strain curve, temperature dependence of viscoelasticity, and modeling of viscoelastic behavior of epoxy/amine systems were the different subjects of our investigation.
