ABSTRACT:
A process for making a structural member wherein bead members are mixed with a selected material and the mixture is compressed and molded into a shape. The compressed mixture is then heated and the bead members removed by melting. The remaining structure, having been thus formed with a plurality of cells therein where the bead members had been removed, can in some embodiments be further heated to a point sufficient to form a strong, lightweight useful structural member, retaining such plurality of cells therein and creating a substantially solid, structural foam member.
