Abstract

The CO2-assisted polymer compression method is a technique for plasticizing polymers with CO2 and crimping polymer fibers. Porous materials with different densities and porosities can be produced by varying the number of laminated layers and the compression rate with the same fiber sheets as the raw material. Based on microsphere repulsion tester analysis, it was found that owing to the viscoelastic effect, the restitution coefficient increased with an increase in porosity. In addition, the type-D hardness decreased with an increase in porosity, which can be explained by the typical relationship between the porosity and Young’s modulus of porous materials.
