This paper reports the study of hollow microballoon-filled epoxy composites also known as syntactic foams with various volume fractions of microballoons. Different mechanical and thermomechanical investigations were carried out to study the elastic and viscoelastic behavior of these foams. The density, void content, and microstructure of these materials were also studied for better characterization. In addition to the experimental testing, a representative 3D model of these syntactic foams was developed to further investigate their elastic behavior. The results indicate that changes in the volume percentage of the microballoons had a substantial impact on the elastic and viscoelastic behavior of these foams. These results will help in designing and optimizing custom-tailored syntactic foams for different engineering applications.
本文报道了对填充空心微球的环氧复合材料（也称为复合泡沫材料）的研究，该材料含有不同体积分数的微球。进行了不同的力学和热机械研究，以探究这些泡沫材料的弹性和粘弹性行为。还研究了这些材料的密度、孔隙率和微观结构，以便进行更好的表征。除了实验测试外，还建立了这些复合泡沫材料的代表性三维模型，以进一步研究其弹性行为。结果表明，微球体积百分比的变化对这些泡沫材料的弹性和粘弹性行为有重大影响。这些结果将有助于设计和优化针对不同工程应用的定制复合泡沫材料。
