Effects of porosity on dynamic indentation resistance of silica nanofoam. [PDF]
, 2017 The dynamic indentation behaviors of monolithic silica nanofoams of various porosities are investigated. When the pore size is on the nm scale, as the porosity increases, despite the decrease in mass density, the resistance offered by silica nanofoam to ...

Syntactic foam supports. Final report [PDF]
, 1980 Foams consisting of blends of a polyimide resin and glass microbubbles were prepared to provide thermal protection and energy absorption. With the selected type of glass microbubble, tests wre conducted to measure the effect of foam formulation, microbubble strength, and molding pressure on certain mechanical, thermal, and environmental properties.

Thermally conductive syntactic foam
, 1976 A low density, high thermal conductivity syntactic foam has been formulated from carbon and graphite microballoons with a polyimide binder resin and graphite fibers. The flexural properties of strength and deflection were increased by using the graphite fibers and the failure mode was increased from a brittle to an elastic mode.

Electrospun Polyamide Nanofiber-Reinforced Hybrid Syntactic Foams
Polymer-Plastics Technology and Engineering, 2016 The potential of polyamide nanofibers towards improving the mechanical properties of syntactic foams is demonstrated. Nylon nanofibers were prepared by electrospinning, and the operating parameters, namely solution concentration and flow rate varied to obtain fibers of requisite dimensions.

Preparation and Evaluation of Microstructure, Compressive and Tensile Strength of Vinyl Ester/Glass Micro Balloon Foams [PDF]
Journal of Advanced Materials in EngineeringSyntactic foams consisting of vinyl ester resin hollow glass microspheres (microballoons) are used in many marine or air structures due to their low density, high stiffness/density ratio, and ability to absorb energy.
