Elastic Moduli of Aluminum-Polyurethane Composites (ALUMERS)

Abstract

In this report, results are given of the bulk modulus measurement of some selected polyurethanes and of the bulk and Young's modulus of these polyurethanes and composites. These composites consist of a matrix of foamed aluminum impregnated with the various polymers. The composites are named 'alumers', a contraction of 'aluminum' and 'elastomer'. These materials are designed to be approximately transparent to sound, since both density and sound speed are close to those for the medium, in this case (sea)water. The foamed aluminum matrix supplies mechanical strength for those applications where the material is used for structural support....
