On the Network Strength of Meta-Aramid Fiber Suspension and Its Relationship to Formation

Advances in Polymer Technology, 2022
Because of poor surface hydrophilicity, meta-aramid fibers readily form flocs by intertwining or interlacing, and this severely affects the uniformity of meta-aramid paper.

Synthesis of new aramid fiber [PDF]

Polymer Science Series A, 2010
A new aramid fiber designed for the fabrication of heat-and-fire-resistant textile products is synthesized. The chemical structure of the initial polymer is a copolymer based on three aromatic diamines—5(6)-amino-2-(p-aminophenyl)benzimidazole, m-phenylenediamine, and p-phenylenediamine—and terephthaloyl chloride.

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.

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.
