An Adaptive Metasurface for Adjustable Magnetic Resonance Imaging Enhancement at 3 T and 7 T: A Feasibility Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultra‐high field (≥ 7 T) and 3 T MRI suffer from B1+ inhomogeneity and signal loss. Conventional metasurfaces that mitigate B1+ inhomogeneity and improve image SNR are “fixed” in nature and designed for a single Larmor frequency. This study demonstrates the feasibility of an adaptive metasurface utilizing voltage‐controlled capacitors ...

Multiscale Modeling of Hole Damage Evolution During Dynamic Installation of Interference Bushings in CFRP

Polymer Composites, EarlyView.
Multiscale modeling for dynamic installatioin. ABSTRACT The dynamic installation of metal interference bushings has demonstrated significant potential for improving the mechanical performance of carbon fiber‐reinforced polymer (CFRP) joints. However, the underlying mechanisms governing the remaining life enhancement remain insufficiently understood ...

Mechanical Properties of Hybrid Natural Fiber–Carbon Fiber‐Reinforced Polypropylene Nonwoven Composites: Influence of Degree of Densification, Fiber Volume Fraction and Laminate Architecture

Polymer Composites, EarlyView.
Reinforcement where it matters: from a homogenious fiber‐reinforced part to a load‐adapted hybrid molded composite part. ABSTRACT Nonwoven composites based on flax fiber (NF)‐reinforced polypropylene (PP) offer a promising route toward sustainable lightweight structures but are limited by moderate mechanical performance.
