Dynamic energy absorption of Cu–W interpenetrating phase composites
The paper presents a study on static compression and dynamic impact properties of Cu–W interpenetrating phase composites (IPCs) with cubic and bio-inspired W skeletons. Strength, failure mechanism, and energy absorption of Cu–W IPCs are investigated. The results show that the energy absorption of Cu...

| Summary: | The paper presents a study on static compression and dynamic impact properties of Cu–W interpenetrating phase composites (IPCs) with cubic and bio-inspired W skeletons. Strength, failure mechanism, and energy absorption of Cu–W IPCs are investigated. The results show that the energy absorption of Cu–W IPCs for both quasi-static and dynamic compression is significantly improved by the addition of Cu. The shape of W skeleton has significant effects on the mechanical properties and failure mechanism of Cu–W IPCs. The cubic W skeleton bears a higher stress than the bio-inspired skeleton. Cracking of the W skeleton and interfacial cracking between the Cu and W skeleton are more likely to occur. The bio-inspired structure Cu–W IPCs exhibit a lower strength but higher energy-absorbing levels for both quasi-static and dynamic compression. |
