.... This paper investigates the effect of embedded PZT crystals on the overall creep behavior of sandwich beams comprising of glass fiber reinforced polymer laminated skins and polymer foam core, which could potentially be used as a damage-detecting smart structure. Uniaxial quasi-static and creep tests were...

It is found that the compressive strength and energy absorption of integrated FGSF composites can be varied based on arrangement of the layers. compressive strength curing functionally graded materials polymer foams resins solidification microballoons syntactic foams...

...Timothy R. Walter; Andrew W. Richards; Ghatu Subhash Tensile and compressive stress-strain responses were obtained for various densities of polymer foams. These experimental data were used to determine relevant engineering parameters (such as elastic moduli in tension and compression, ultimate...
