对泡沫镍（平均孔径约为2.7 mm，孔隙率为93.1%）孔棱进行环氧树脂覆层复合，获得孔棱呈复层结构的泡沫镍/树脂多孔复合材料。对所得复合样品进行压缩性能实验，重点分析复合体的机械强度。结果表明：复合样品的压缩强度和比强度均显著高于原泡沫镍。当泡沫镍（体密度ρ _r约0.6 g·cm^-3）施加覆层制成泡沫镍/树脂复合样品（体密度约0.72~0.82 g·cm^-3）后，其压缩强度从0.75 MPa提高到2.24~2.68 MPa，其对应比强度从1.23 MPa·cm³·g^－1提高到3.09~3.27 MPa·cm³·g^－1。复合样品的压缩强度与孔隙率符合基于八面体模型理论得出的对应数理关系。根据对应力学模型可知，复合样品整体失效由孔棱芯部优先破坏造成。

The nickel foam （the average pore diameter is about 2.7 mm，and the porosity is 93.1%） is used for the epoxy resin to coat the pore-struts， and the porous nickel foam/epoxy resin composite is obtained with such pore-struts as a multi-layer structure. The compression performance experiments are conducted on the obtained composite samples， and the mechanical strength is emphatically analyzed. The results show that the compressive strength and the specific strength of the composite samples are both significantly higher than those of the original nickel foam， respectively. When the nickel foam （with a bulk density of about 0.6 g·cm^-3） is coated to make nickel foam/resin composite samples （with a bulk density of about 0.72-0.82 g·cm^-3）， the compressive strength increases from 0.75 MPa to 2.24-2.68 MPa， and the specific strength increases from 1.23 MPa·cm³·g^-1 to 3.09-3.27 MPa·cm³·g^-1. The relationship between compressive strength and porosity of composite samples conforms to the corresponding mathematical relationship based on the octahedral model theory. According to the relevant mechanical model， the overall failure of the composite samples is caused by the priority failure of the pore-strut core.
