本文介绍了一种新型的集成成型制造功能梯度（FG）复合环氧泡沫塑料，以控制高冲击能量吸收的机械性能的分布。为了控制力学性能，在FG环氧泡沫中的密度分布梯度的轻质微球在基体环氧树脂在固化过程中的浮动现象。通过对微球分级前模具的翻转处理，可以制备出密度在较宽范围内渐变连续分布的FG环氧泡沫塑料。静态压缩试验表明，由于密度分布的梯度性，泡沫材料具有较高的机械能吸收能力。
This paper describes novel integrated molding for fabrication of functionally-graded (FG) syntactic epoxy foams to control distribution of the mechanical properties for highly impact energy absorption. In order to control mechanical properties, the density distributions in the FG epoxy foams were graded by floating phenomenon of the light-weight micro-balloons in the matrix epoxy resin during the curing process. By the turning procedure of the mold before grading the micro-balloons, the FG epoxy foams having the gradual and continuous distributions of density in wide range could be produced. The static compression tests of the fabricated FG epoxy foams suggested that the foams had high absorption of mechanical energy since the foams collapsed progressively due to the grading of the density distribution.
