研究了丁腈羟增韧环氧树脂的力学性能和形态结构．丁腈羟的用量、丁腈羟中丙烯腈的含量、固化条件对所形成的微区尺寸都有较大影响，并进一步影响固化物的力学性能．
The mechanical properties and morphology of nitrile hydroxyl toughened epoxy resin were studied. The amount of nitrile hydroxyl, nitrile hydroxyl acrylonitrile content, curing conditions on the formation of the micro-size have a greater impact, and further affect the mechanical properties of cured.
