Abstract

For a better understanding of the mechanical properties of absorbent, it is essential for the evaluation of absorbent experiments. In recent years the use of functionally foam as the energy absorber has been remarkable. So far the functionally foam is not produced in industrial methods. Previous research on functionally foam is a model in the software. The idea of discrete functionally foam production method is used in this article for the first time. In these tests the gradient mode density in the sample test used Polyurethane foams with different mechanical properties and density were produced and made functional foam inside the profiles are located. In this research the functional foams derived for the axial gradient, radial gradient, and bi-directional were studied. Compressive static loading experiments can be used to design an optimal mechanical property of absorber. The results of this research reveal that specific energy absorbed of axial functional profiles is very favorable.
