Abstract

This chapter gives an overview on the toughening thermosets using reactive liquid natural rubber. The preparation method of liquid rubbers from natural rubber and toughening mechanism of thermosets resin are discussed. The use of liquid natural rubber (LNR) and liquid-epoxidized natural rubber (LENR) as impact modifier for toughening thermosets showed that the optimum rubber content is at lower percentages of rubber. The mechanical and morphological properties of toughened polyester and epoxy blends with different concentrations of both LNR and LENR in the blend were examined. Results showed an increase in tensile strength which proved better interaction of rubber particles with the resin. Morphological observation showed that the diameter of LENR particles dispersed in the epoxy matrix was much smaller than the LNR particles. The difference in morphology observed in both epoxy composite systems was attributed to the different chemical reactivities of LNR and LENR. The study showed that the miscibility and interfacial properties played important roles in the toughening process of thermoset resin.
