应用方差分析来模拟混合泡沫的机械性能。研究中使用的控制变量是玻璃纤维和芳纶纤维的纤维重量分数，所有泡沫样品的密度相似（~250 kg/m3）。分析的响应是压缩和剪切载荷的弹性模量和强度。检查了混合泡沫样品的微观结构，并研究了纤维类型对泡孔几何形状和分布的影响。结果表明，混合泡沫中的每种纤维类型对压缩和剪切性能都有显着影响，并且纤维重量分数影响性能的各向同性。利用统计模型来预测混合复合材料泡沫性能是一种合适的工具，可以提供工艺变量对泡沫性能影响的全局视角。
An analysis of variance was applied to model the mechanical properties of hybrid foams. The controlled variable used in the study was the fiber weight fraction of glass and aramid fibers, and all foam samples were of similar density (∼250 kg/m3). The responses analyzed were elastic modulus and strength for compressive and shear loading. The microstructure of the hybrid foam samples was examined and the effects of fiber type on the cell geometry and distribution were studied. The results showed that each fiber type in hybrid foam had significant effects on the compression and shear properties and the fiber weight fraction affected the isotropy of the properties. The utilization of a statistical model for predicting hybrid composite foam properties is an appropriate tool that affords a global perspective of the influence of process variables on foam properties.
