摘要

In this work, the effect of a thermoplastic modifier (ABS) on the mechanical properties of an epoxy resin (DGEBA) cured with a diamine (1,3-BAG) was studied. The experiments were carried out at three different temperatures. The effect of the temperature on the mechanical behaviour has been investigated too. It was observed that the rise in temperature improved the duc-tility of the modified epoxy systems. The presence of ABS did not produce a clear enhancement in the toughening of the epoxy resin, this behaviour was explained as a function of the high crosslink density reached in the curing cycle.
