Abstract / Description of output

The mechanical and fracture performance of a modified epoxy resin cured with an anhydride hardener containing block copolymer (BCP) and/or core-shell rubber nanoparticles (CSR) were investigated in the current work. The effect of adding an additional resin, i.e. triglycidyl ether of meta amino phenol (TGMAP) to the bis-F based epoxy resin was also investigated. The fracture energy of the pure bis-F based epoxy increased slightly from 0.088 kJ/m2 to 0.120 kJ/m2 due to the addition of 7 wt% of the TGMAP to the bis-F epoxy. The fracture energy increased to 0.448 kJ/m2 and 0.938 kJ/m2 when 12 wt% of the CSR nanoparticles and 10 wt% of di-block-copolymer were added to the modified epoxy respectively. Furthermore, the addition of di-block-copolymers and core shell rubber particles yielded hybrid epoxy polymer nanocomposites containing an equal wt% of BCP and CSR nanoparticles. The measured toughness of the hybrid materials was related to the degree of dispersion of both nanoparticle phases in the epoxy polymer matrix. Toughening mechanisms were identified using fractography studies.
