Residual compression mechanical properties after low-speed impact for laminated stitched carbon fiber reinforced aluminum matrix composite

Journal of Aeronautical Materials, 2022
Using aluminum alloy ZL301 as matrix and carbon fiber laminated suture fabric as reinforcement, carbon fiber reinforced aluminum matrix (Cf/Al) composites with laminated stitch were prepared by vacuum pressure infiltration process. Through the drop hammer impact test at room temperature, the behavior of impact load and energy change with time was ...

Ab Initio Study on 3D Anisotropic Ferroelectric Switching Mechanism and Coercive Field in HfO2 and ZrO2

Advanced Functional Materials, EarlyView.
This study uncovers a new switching mechanism in HfO2 and ZrO2, where the absence of a non‐polar layer along the a‐direction induces interaction between polar layers. Consequently, the switching barriers for growth are lower than those for nucleation in this direction, leading to a size‐dependent coercive field that matches experimental observations ...
