Abstract

Abstract

The mixed cellular materials with soft matrix are a new type of cushioning and protective materials which have excellent energy absorption properties. In order to study the effect of strain rate on the mechanical behaviors of this kind of materials, uniaxial tensile and compression experiments were conducted on the artificial cartilage foam (ACF) material, at different velocities to obtain the stress-strain curves of the ACF material under different strain rate conditions. Based on the obtained stress-strain curves, the elastic moduli and material strengths of the ACF material were gained under different strain rate conditions. And the comparative tests of the ACF material and expanded polypropylene (EPP) material of the same size and thickness under multiple impacts were carried out by a drop-hammer impact test machine. By comparing the impact responses of the two materials under single and multiple impact loads, the energy absorption characteristics, and the stability of the energy absorption characteristics of the two materials were analyzed. The results reveal that the ACF material is a strain rate-sensitive material, and the stress-strain curves under different strain-rate conditions take on the same trend. The elastic modulus, tensile and compressive strengths of the material gradually increase with the increasing strain rate. Under the action of 50-J impact energy, the ACF material can absorb more than 96% of the impact energy, higher than the 70% of the impact energy absorbed by the EPP material. Moreover, the maximum displacement of the ACF material is only 40% of that of the EPP material. Therefore, the ACF material has more excellent energy absorption performance than the EPP material. The peak force, maximum displacement, and energy absorption ability of the ACF material were almost unchanged after five impacts. Compared with the EPP materials, the ACF material has more favorable recoverability and more stable repeated impact resistance. The research of the work can provide an experimental basis for the application of the mixed cellular materials with soft matrix in multiple impact protection.
