Abstract

The mechanical behavior of microcellular open-cell foams prepared by a thermally induced phase separation process are investigated. The foams studied were prepared from isotactic polystyrene, polyacrylonitrile, and poly(4-methyl-1-pentene) (rigid foams), and polyurethane and Lycra (elastomeric foams). Their densities were in the range 0.04–0.27 g/cm3. Conventional polystyrene foams were used for comparison. The moduli and collapse stresses of these foams were measured in compression and compared with the current constitutive laws which relate mechanical properties to densities. A reinforcement technique based on the in-situ precipitation of silica was used to improve the mechanical properties.

The ratio of yield stress/modulus is calculated for the polystyrenes given in Modern Plastics Encyclopedia, edited by Agranoff, J., (McGraw-Hill Inc., 61, NewYork, NY 1984–1985) p.453, and an average ratio of 0.0265 is obtained; by using this ratio, and the modulus given in Ref.10, the yield stress of IPS is calulatd to be 148 MPa.Google Scholar
