Dynamic Modeling and Simulation of Morphing Wing Aircraft Considering Rigid‐Elastic Coupling Effects

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT During the morphing process, the dynamic modeling of the morphing wing aircraft presents the characteristics of rigid‐elastic coupling effects, moving boundaries, and low computational efficiency. Meanwhile, parameters such as aerodynamic forces/moments, center of pressure, center of mass, and moment of inertia would also change significantly,

Mechanical and Electrochemical Performance of a PETEA‐Based Solid‐State Electrolyte for Multifunctional Structural Battery Composites

Nano Select, EarlyView.
Multifunctional structural battery composites can store electrical energy while bearing mechanical loads, thereby reducing parasitic mass and volume. We present a novel solid‐state PETEA‐based electrolyte, which can be cured in situ after infiltration into the reinforcement fibers in its monomer form.

Impact and Post‐Impact Properties of Carbon Fiber Fabric Laminates Reinforced With Carbon Nanofibres

Polymer Composites, EarlyView.
Carbon nanofiber addition on the low‐velocity impact response of carbon fiber laminates. ABSTRACT The use of carbon fiber reinforced polymers (CFRPs) is limited by their susceptibility to low‐velocity impact (LVI) damage. This study investigates the effect of incorporating 0.75 wt.% carbon nanofibres (CNFs) into the epoxy matrix of carbon fiber fabric ...

Application of 3D scanning technology in Royal Malaysian Air Force Industrial Revolution 4.0‐based aircraft maintenance

IET Networks, EarlyView., 2022
Abstract 3D scanning is rapidly becoming a key maintenance tool. Aerospace was a pioneer in adopting 3D scanning technology because aircraft manufacture and maintenance require precision. Monitoring deterioration, removing components for maintenance, and verifying covert operations are not practical or helpful without technology.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...
