“…This difference is reasonable since the compressive strength of the syntactic foam in the study by Swetha and Kumar [2] was approximately times stronger than that of the syntactic foam in this study. Meanwhile, Walter et al [36] reported the similar energy absorption of epoxy-based syntactic foam ranging from 200 -2000 kJ/m when materials with similar strength were used. Therefore, the glass microspheres partially replaced by the crumb rubber yielded higher energy absorption but lower impact impulse capacity.…”

Syntactic foam is a lightweight and strong material which can be used in marine and aeronautical applications. However, the brittleness of the material limits its application to a broader range. Adding crumb rubber to the syntactic foam can increase its energy absorption capacity. The effect of crumb rubber on the fracture toughness and energy absorption capacity of 2-phase and 3-phase syntactic foam is evaluated under both static and impact loads. The experimental results have shown that the fracture toughness of the 2-phase rubberized syntactic foam increased by 8% while an increase of 22% of its fracture energy was observed. Under quasi-static loads, the 3-phase rubberized syntactic foam showed decreases in the compressive strength and elastic modulus but an increase in the energy absorption capacity as compared to the syntactic foam without crumb rubber. In addition, the impact energy absorption of the 3-phase rubberized syntactic foam increased by 24% as compared to that of the 3-phase syntactic foam without crumb rubber.
