Although epoxy paints are widely and increasingly used
very little information is available concerning the conditions
that affect stable (adhesive) failure or unstable (cohesive)
'crack jumping' failure. Consequently the parameter of
fracture surface energy (y) has been chosen to characterise the
fracture properties of five epoxy resins based on diglycidyl
ether bisphenol A 'DGEBA' cured with trimellitic anhydride 'TMA'.
Principles of fracture surface energy measurement previously
applied to structural adhesive have been applied here to epoxy
