A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Antimicrobial Polymeric Materials; Cellulose and m- Aramid Composite Fibers [PDF]

Journal of Engineered Fibers and Fabrics, 2007
Cellulose and m-aramid were dissolved in an ionic liquid, and dry-jet wet spinning was employed to prepare composite fibers which could be rendered antimicrobial through exposure to chlorine bleach. The small domains of the m-aramid allowed a much higher

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4037-4060, September 2026.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Optimizing p-aramid copolymer superfibers: The synergistic effect of solution rheology and fiber structure

Polymer Testing
Para-aramid (p-aramid) fibers have gained significant attention in lightweight vehicle and optical cable industries. However, the use of harsh sulfuric acid-based processing limits their widespread adoption. As a promising alternative, p-aramid copolymer
