“…Recently Kim and Oh [6], and Gupta et al [7] have also reported that failure mode of a syntactic foam with relatively high concentration of resin under uniform compression was by shear on inclined planes. Gupta et al [7,8] highlighted that the shear failure mechanism is affected by specimen aspect ratio. Kim and Plubrai [1] studied low density (0.11 -0.15 g/cc) glass/epoxy syntactic foams and found that compressive failure was of 'layered crushing'.…”

Novel syntactic foams for potential building material applications were developed using starch as binder and ceramic hollow micro-spheres available as waste from coal-fire power stations. Foams of four different micro-sphere size groups were manufactured with either pre-or post-mould gelatinization process. They were of ternary system including voids with a foam density range of approximately 0.33 -0.44 g/cc.Compressive failure behaviour and mechanical properties of the manufactured foams were evaluated. Not much difference in failure behaviour or in mechanical properties between the two different processes (preand post-mould gels) was found for a given binder content. Compressive failure of all syntactic foams was of shear on plane inclined 45° to compressive loading direction. Failure surfaces of most syntactic foams were characterised by debonded micro-spheres. Compressive strength and modulus of syntactic foams were found to be dependant mainly on binder content but mostly independent of micro-sphere size. Some conditions of relativity arising from properties of constituents leading to the rule of mixtures relationships for compressive strength and to understanding of compressive/transitional failure behaviour were developed. The developed relationships based on the rule of mixtures were partially verified. Some formation of starch webs on failure surfaces was discussed.

“…Therefore, these foams were considered good materials for thermal and sound insulation, among others. Other researchers studied failure modes in syntactic foams by experimental methods [12][13][14], but there has not been found any report on both theoretical and experimental studies yet.…”

Limit load and failure mechanisms of soda lime glass foam

et al. 2018

Foamed glass is widely used in the industry as an insulating material. However, its mechanical properties are not well-investigated yet. Foamed glass is produced from glass waste that causes discrepancy in mechanical properties of the final product. This paper shows a way to increase the limit of the load capacity of foamed glass, which is very fragile and sensitive to mechanical and thermal loading conditions. In this paper, three different methods of load application on cellular glass structure (rough contact, resin and flour interfaces) and their influence on failure mechanisms were investigated in detail. The results of numerical analyses, based on finite elements method and compression strength tests using the digital image correlation method, indicate that the overall strength of the material is limited by boundary effects. A careful adjustment of the interface property is the main factor to draw useful conclusions and to extend load limits of cellular glass in engineering applications.

“…Syntactic foams are sometimes described as three-phase composites, considering interstitial voids within the matrix to be the third phase [2,3]. Compared with standard foams (containing blown gas bubbles only), syntactic foams are often preferred in weight-sensitive applications, for which their enhanced mechanical properties and tailorability make them useful [4,5].…”

Development of a Polymer Based Syntactic Foam for High Temperature Applications

et al. 2014

Syntactic foams are one of the most widely used close cell structured foams. They are used in applications for naval, aeronautical, aerospace, civil, industrial, and automotive engineering due to good acoustical attenuation, excellent strength to weight ratio, vibration isolation, and dielectric properties. These foams are fabricated by incorporation of hollow particles in a matrix material. The most preferred matrix materials are polymers. In this study silicone resin (useful temperature range −53• C to 232• C) was selected as a binder material. Glass bubbles were incorporated into the silicone resin at three dierent mass percentages (10%, 20%, and 30%). The density of the silicone was reduced more than 50% by 30% glass bubble contribution. The foam mechanical properties were investigated in a room temperature and after heat treatment at 500• C by quasi-static compression experiments. Microstructural transitions by the temperature raises were examined by using scanning electron microscopy pictures. It was observed that the increase of glass bubble percentage in silicone rubber enhanced the energy absorption properties in the heat treated and room temperature specimens. Plateau stress and densication amount were improved under quasi-static compression load by the glass bubble percentage increase. It can be said that developed syntactic foams can be used in heat resistant, low weight and high compression strength exigencies.
