From Magnetic Fibers to Paper Architectures: A Lightweight Strategy for Robust Low-Frequency Microwave Absorption. [PDF]

Adv Sci (Weinh)
A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.

Dyeing of m-Aramid Fibers in Ionic Liquids [PDF]

Polymers, 2020
Aramids represent a class of high-performance fibers with outstanding properties and manifold technical applications, e.g., in flame-retardant protective clothing for firefighters and soldiers. However, the dyeing of aramid fibers is accompanied by several economic and ecological disadvantages, resulting in a high consumption of water, energy and ...

Anti-Chemical Properties of Modular Protective Material

Вестник войск РХБ защиты, 2023
Previously, we developed the principle of constructing modular materials with specified properties, according to which organometallic composites, with nanoscale enzyme complexes introduced into them, are applied to a unified fabric platform.

Ozone Effect On the Properties of Aramid Fabric

AUTEX Research Journal, 2017
The limitation of aramid fiber is its surface property, which results in its very poor interfacial adhesion to most of commercial resins. In order to improve the surface property of the aramid fiber, ozone treatment was carried out in this work.

Effect of stitch and biaxial yarn types on the impact properties of biaxial weft knitted textile composites

Science and Engineering of Composite Materials, 2013
Within the scope of experiments, the effects of stitch yarn type, such as aramid, glass, and nylon, and biaxial, warp, and weft yarn type, such as aramid and glass, on biaxial weft knitted (BWK) composites were investigated.

Strength and Durability Study of Concrete Structures Using Aramid-Fiber-Reinforced Polymer

Fibers, 2019
Fiber-reinforced polymer (FRP) is an important material used for strengthening and retrofitting of reinforced concrete structures. Commonly used fibers are glass, carbon, and aramid fibers.

Continuous Fiber-Reinforced Material Extrusion with Hybrid Composites of Carbon and Aramid Fibers

Applied Sciences, 2022
An existing challenge in the use of continuous fiber reinforcements in additively manufactured parts is the limited availability of suitable fiber materials. This leads to a reduced adaptability of the mechanical properties to the load case.

Improvement of the Mechanical Properties by Surface Modification of ZnCl₂ and Polydopamine in Aramid Fiber Composites

Applied Sciences, 2022
Although aramid fiber has the advantage of excellent chemical and mechanical properties, the performance of the composites may be reduced due to the low interfacial adhesion between the fabric and the matrix.
