在理论分析的基础上，讨论了梯度功能泡沫材料作为冲击吸能材料的作用，提出了梯度功能泡沫材料的制备工艺。在理论分析中发现FG泡沫由于逐渐局部破裂或缓冲而被发现是有用的作为冲击吸收器。提出了FG泡沫塑料的制备工艺。在该工艺中，在固化基体树脂之前进行微球的分级分散。通过数值分析，证实了在微球悬浮的基础上预测的FG泡沫中的密度分布。最后，进行压缩试验，以评估力学性能。
Function of functionally-graded (FG) foams as energy absorption material for impact was discussed on the basis of theoretical analysis, and fabrication process of the foams was proposed in the paper. The FG foams were found to be useful as impact absorber due to progressively local fracture or cushion in the theoretical analysis. Next the fabrication process of the FG foams was suggested. The graded dispersion of the micro-balloons was conducted before curing the matrix resin in the process. The density distributions in the FG foams were confirmed to be predicted by the numerical analysis on the basis of floating the micro-balloons. Finally, compression tests were carried out to evaluate mechanical properties.
