Description
Summary:We performed the complex static and dynamic mechanical characterization of cross-linked polyethylene foams; we investigated the effect of foam density on various mechanical properties and the relationship between cell structure and mechanical behavior. The impact damping and energy absorption properties of the foams were determined by falling weight impact tests, while static mechanical properties were determined by compression and compression set tests. The experimental results validated our hypothesis that the relationship between the above-mentioned mechanical properties and density can be described with the power law with good approximation.
