Wear failure mechanism analysis of self-lubricating fabric composites at high temperature
Journal of Industrial Textiles, 2022 The friction and wear properties of self-lubricating fabric composites were closely related to fiber properties. In this paper, polyimide (PI), polyetheretherketone (PEEK), polyisophthalamide (PMIA) and cyclic aramid (Aramid III) fibers were selected as ...

Electrospinning of p-Aramid Fibers
Macromolecular Materials and Engineering, 2015 Electrospun poly (p-phenylene terephthalamide) (PPTA) fibers with diameters between 275 nm and 15 µm were obtained from anisotropic solutions, albeit that the spinning process was difficult to control. Key solution parameters like conductivity, surface tension, and viscosity were used to compare the spinnability of these anisotropic solutions with ...

Journal of Materials Research and Technology, 2017 For personal protection against high kinetic energy projectiles, multilayered armor systems (MAS) are usually the best option. They combine synergistically the properties of different materials such as ceramics, composites and metals. In the present work,

Reinforcing effect of aramid fibers on fatigue behavior of SBR/aramid fiber composites
Polymer Testing, 2019 Abstract This paper investigates the correlation between fatigue performance and static tensile behavior of fiber reinforced rubber materials and presents change of fiber reinforced effect during fatigue process. A rough aramid fiber (AF) surface, which is helpful for combining AF and rubber matrix, was achieved by etching AF in NaOH/CH3CH2OH ...

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries
Advanced Materials, EarlyView.We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

Advanced Materials Interfaces, EarlyView.Ultrathin MXene/EMF composite foams achieve a specific shielding efficiency of 749.6 dB.dB·cm3$\mathrm{dB}\cdot {\mathrm{cm}}^{3}$/g, while the silver‐enhanced MXene/Ag/EMF reaches 81.4 dB shielding effectiveness at just 1.0 mm thickness. Both composites exhibit rapid Joule heating, retain stability up to 250∘C$^\circ{\rm C}$, and withstand 1000 ...
