Abstract:

Article Preview

Low density syntactic foam monolayer slices, which were made of epoxy resin matrix and plastic microballoons (MB), were fabricated by rolling process with thickness controlled at 200μm. Density of monolayer slice ranges from 0.500g/cm3 to 0.996g/cm3 and it is designed to fit power law equation. The volume percentage of plastic microballoons in the monolayer pellets varies from 16.61% to 58.06%. The slices were characterized by optical and scanning electron microscopy, and measurement of density and sound wave velocity. The density, glass transition temperature and acoustic impedance were observed to vary with the volume percentage of plastic microballoons in the composite. Graded syntactic foams were fabricated by stacking slices of different density in a sequence of density gradient and the slices were bound together with adhesive made of epoxy resin-hardener under the pressure of 5MPa.
