Abstract: Syntactic foams are materials including hollow microspheres distributed throughout a cured polymeric resin. Hollow microspheres within syntactic foams, including collapsible shells that enclose empty cavities, can serve as receptacles to capture environmental constituents upon applied temperature and pressure. An epoxy formulation including of EPON™ 828, HELOXY™ 61, and TETA was combined with hollow glass microspheres with isostatic crush strengths of 300, 3000, and 10,000 psi.
