AI Technical Summary
Technical Problem
Aramid fibers have a smooth surface morphology that weakens interfacial bonding strength with resins, and existing surface treatments to enhance this often impair mechanical properties and are unsuitable for large-scale production.
Method used
Aramid fibers are recycled through ionic crosslinking, forming a unidirectional micro-wrinkle pattern via a simple spinning process, maximizing surface polar group exposure without post-processing, using alkaline and proton-donating solutions with metal cations to induce self-assembly and protonation reactions.
Benefits of technology
The method enhances chemical and physical bonding strength with matrices, creating high-performance composite materials with improved interfacial bonding.

Abstract
The present invention relates to a regenerated aramid fiber and a manufacturing method therefor, and, more particularly, to a manufacturing method for a regenerated aramid fiber in which fine surface wrinkles are formed due to surface instability, caused by ionic crosslinking, between a hard surface part and a soft core part.
