✦ Synopsis

Ahstrati-A comparison of mechanical behaviour was made between an epoxy resin cured by microwaves and one cured thermally. By tensile tests, it was found that the microwave cured resin has a little higher tensile strength and Young's modulus. This difference was considered to be attributed to the greater homogeneity of the microwave cured resin. After ageing in water, the microwave cured resin maintained its advantage of mechanical properties over the thermally cured one. The tensile strength and Young's modulus of both resins increased with the strain rate. The fracture surfaces show some significant mechanisms of rupture and of an ageing effect.
