Abstract

Maleated styrene-ethylene-butylene-styrene block copolymer (SEBS-g-MA) and epoxy monomer, individually or in combination, are used to toughen polyamide 6/glass fiber composites. The epoxy monomer enhanced interaction between polyamide 6 and glass fiber. SEBS-g-MA rubber is uniformly dispersed in polyamide 6 matrix caused by the preferred compatibilizing reaction between the anhydride group of rubber and the amine terminal group of polyamide 6. The addition of epoxy does not affect the fine dispersion of SEBS-g-MA. Polyamide 6/glass fiber binary composites are brittle. The addition of epoxy monomer alone does not change their brittle features. Similarly, in the absence of epoxy monomer, adding 20 wt % of SEBS-g-MA to polyamide 6/glass fiber composites does not greatly increase the tensile ductility. Only when both SEBS-g-MA and epoxy monomer are present in some combination, do the polyamide 6/glass fiber composites show prominent ductile characteristics, such as stress-whitening and necking. This synergistic effect of epoxy monomer and SEBS-g-MA also imparts higher notched impact strengths to the ternary composites.
