“…Syntactic foams are often used in civil engineering as substitute for wood or as core materials of sandwich structures [10]. Another field of application is aeronautical and aerospace engineering, e.g., as ablative shields for space vehicles [11].…”

The quasi-static, static, and cyclic compressive behavior of a novel epoxy matrix cellular composite reinforced with glass foam granules is investigated. Three different grain-size fractions of the granules are used: 0.5-1, 1-2, and 2-4 mm. The density of the cellular composite varies between 0.65 and 0.82 g/cm 3 . The material exhibits high specific compressive strength and stiffness within the class of cellular materials; these properties can be varied using appropriate size of granules. The glass foam granules increase the stiffness of the cellular composite compared to neat epoxy foam with the same weight. The measured elastic properties are in good agreement with results obtained from analytical and numerical homogenization methods. The fatigue behavior is determined in static tests and in cyclic tests at 1 and 20 Hz on one type of cellular composite. The fatigue process for cyclic loading is a result of an interaction between static and cyclic damage. The sensitivity to static damage is found to be higher than to cyclic damage. The damage behavior is investigated by evaluation specimen's stiffness and using scanning electron microscopy.

“…Other applications include ablative heat shields and substitutes for wood. For such applications, several types syntactic foams have been employed, such as high strength epoxy resin-glass microballoon syntactic foams (2), epoxy resin-carbon microballoon syntactic foams (3), phenolic resin-phenolic microballoons-Nylon powder syntactic foams (4), and glass fiber reinforced polyester resin syntactic foams with polyvinylidene chloride microballoons (5).…”
