Abstract: The studies done by domestic and foreign scholars on the mechanical behavior of fiber reinforced foams are reviewed briefly in this paper. The fabrication technique and microstructure of fiber reinforced foams are introduced simply. The mechanical properties of the materials and some works of the authors are reported emphatically. The basic mechanical properties, reinforcement and failure mechanisms, effect of temperature, the length of fiber and the influence of the fraction of components and surface treatment on the mechanical behavior are included. The research trends of this kind of materials in the future are prospected.
