Epoxy Resins in Electron Microscopy

A method of embedding biological specimens in araldite 502 (Ciba) has been developed for materials available in the United States. Araldite-embedded tissues are suitable for electron microscopy, but the cutting qualities of the resin necessitates more than routine attention during microtomy. The rather high viscosity of araldite 502 also seems to be an unnecessary handicap. The less viscous epo...

Effect of structure on thermal behaviour of epoxy resins

The paper deals with the curing behaviour of diglycidyl ether of bisphenol-A (DGEBA) using three novel multifunctional aromatic amines having phosphine oxide and amide-acid linkages. The amines were prepared by reacting tris(3-aminophenyl)phosphine oxide (TAP) with 1,2,4,5-benzenetetracarboxylic acid anhydride (P)/4,4-(hexafluoroisopropylidene)diphthalic acid anhydride (F)/3,3,4,4-benzophenonet...

On the velocity-dependent fracture toughness of epoxy resins

In a recent paper [1], Drs Selby and Miller described three methods of determining the fracture toughness (R), or equivalently, the fracture surface energy (23') for an epoxy resin. These methods are respectively (a) Berry's method, (b) Irwin-Kies equation and (c) Gurney's irreversible work area method. While the experimental data obtained from tapered double-cantilever beam (TDCB) specimens su...
