Effect of strain rate on deformation behavior of aluminum matrix composites with Al2O3 nanoparticles
Low cost, high activity, and long-term durability are the main requirements for commercializing fuel cell electrocatalysts. Despite tremendous efforts, developing non-Pt anode electrocatalysts with high activity and long-term durability at low cost remains a significant technical challenge. Here we report a new type of hybrid Pd/PANI/Pd sandwich-structured nanotube array (SNTA) to exploit shape...
Abstract Sandwich construction has proven to be an excellent low-density multifunctional design for a wide range of applications in ballistic protection, energy absorption, and thermal insulation. Based on the bulletproof effect each layer sandwich structure, this paper expounds summarizes material properties that can used as layer. The mechanical ultra-high strength aramid (Kevlar) molecular w...
In this paper, high density rigid polyurethane foam is used as sandwich skeleton and shear thickening fluid material core. A fluid/polyurethane structure with light impact resistance was designed fabricated. High strain rate test carried out. It found that STF-2/PU reached the peak load of 4978N in 13 ms after receiving 20 J energy, energy absorption ratio 43%. The honeycomb prepared by seconda...
