The microstructure and mechanical property of the composite were observed. The results indicate that the distribution of Al2O3 particles in the composites is uniform. The Al/ Al2O3 metal matrix composites can be easily prepared by adjusting the time of blowing oxygen. 试验表明,复合材料中的Al2O3质点分布均匀,通过调节吹氧时间,可方便地制备Al/Al2O3复合材料。
Results show that the resultant foams have outstanding thermal stability and mechanical properties, while the morphology and dielectric properties of BDM/ BA foams are depended on the content of blowing agent. 研究结果表明,泡沫材料具备良好的耐热性和力学性能,且泡沫材料的形态结构与介电性能随着发泡剂含量的变化而变化。
