Elastic properties of highly anisotropic thin poly(propylene) foams

Abstract

In this letter, elastic properties of highly anisotropic cellular poly(propylene) films are reported. The material shows peculiar elastic properties compared to other foams in the literature. The data is displayed as the relative Young's modulus $E^{\ast }/E_s$ versus relative density ${\rho }^{\ast }/{\rho }_s$. Almost all the data from the literature are located on the region $E^{\ast }/E_s=({\rho }^{\ast }/{\rho }_s{)}^n$ with $1\le n\le 6$. The introduced material on the other hand have lower relative Young's modulus at high relative densities, $n\ge 6$.
