N2 - This paper investigates the tensile properties and fracture toughness of a liquid rubber-modified highly crosslinked epoxy cured using 4,4 diaminodiphenyl sulphone (DDS/LR). The results for DDS/LR epoxy in relation to rubber and matrix properties are also compared with those of rubber-modified lowly crosslinked epoxy systems, namely, liquid rubber-modified piperidine cured epoxy (Piperidine/LR) and core-shell-rubber modified piperidine cured epoxy (Piperidine/CSR). It was found that highly crosslinked DDS/LR epoxy has a higher tensile strength than that of either Piperidine/LR or Piperidine/CSR epoxy, while it shows only a moderate increase in the fracture toughness.
