Lightness and high strength are among the two of the most crucial factors in material selection for advanced engineering applications such as marine, aerospace, deep sea equipment, civil, industrial, and automotive engineering. The rapid growth of syntactic foams in these application areas has motivated research and development activities on syntactic foams. In this study, the conventional mold casting technique (CMCT) was used for the production of three-phase syntactic foams. Epoxy resin was utilized as matrix material, glass micro balloon (S22) with a density of 220 kg/m3 and EPS beads with 3 different densities were used as filling material. The average densities of EPS beads used in the study were 10 kg/m3, 18 kg/m3, and 30 kg/m3, respectively. The effects of the densities of the three-phase syntactic foams produced on the compression performance were evaluated. Compression behavior was experimentally investigated at room temperature using a computer-controlled INSTRON 5982 mechanical test system according to the ASTM C365/ C365M-16 standard. The densities of the three-phase syntactic foams obtained vary between 469 kg/m3 and 487 kg/m3. As a result of the study, it was observed that the compressive strength of the syntactic foams increased from 5.91 MPa to 7.77 MPa depending on the increase in density. The results showed that the relationship between compressive strength and foam density is linear. ORCID NO: 0000-0002-4060-5608
