We would like to produce a lightweight epoxy part to provide thermal insulation. We have available hollow glass beads for which the outside diameter is 1/16 in. and the wall thickness is 0.001 in. Determine the weight of beads that must be added to the epoxy to produce a one-pound composite with a density of 0.65 g/cm3 . The density of the glass is 2.5 g/cm3 and that of the epoxy is 1.25 g/cm3 .
