“…Nano-fibrils consist of stacks of crystallites separated by thin non-crystalline plates, portions of which are spanned by inter-crystalline bridges giving a shish-kebab structure [8]. Studies show that the key morphological features of the structures of the UHMWPE fiber at different length scales depend on the process history [9].…”

Ballistic impact induces multiaxial loading on Kevlar ® and polyethylene fibers used in protective armor systems. The influence of multiaxial loading on fiber failure is not well understood. Experiments show reduction in the tensile strength of these fibers after axial and transverse compression. In this paper, we use molecular dynamics (MD) simulations to explain and develop a fundamental understanding of this experimental observation since the property reduction mechanism evolves from the atomistic level. An all-atom MD method is used where bonded and non-bonded atomic interactions are described through a state-of-the-art reactive force field. Monotonic tension simulations in three principal directions of the models are conducted to determine the anisotropic elastic and strength properties. Then the models are subjected to multi-axial loads-axial compression, followed by axial tension and transverse compression, followed by axial tension. MD simulation results indicate that pre-compression distorts the crystal structure, inducing preloading of the covalent bonds and resulting in lower tensile properties.

“…For wool fibers, in 1949, Hock and McMurdie observed that cortical cells were made of fine microfibrils . The studies on natural fibers established the foundation of the theories of fiber fine structure . In a large number of published papers, it is extended to the other man‐made fibers and partially crystalline polymers, where supramolecular structures realized .…”

“…It was found that cellulose consists of completely individualized microfibrils having a thickness from 25 to 40 nm . The subject of structural mechanics of fibers, which explains the relation between mechanical properties of these small particles and the mechanical properties of the whole assembly, has benefitted from realizing these small size particles, where the stress‐strain relation of natural fibers (cotton, wool, silk, etc) is explained in terms of the mechanical properties of constituent nanomaterials …”

This review is about the naturally formed and intentionally produced nanofibrils or nanofibers (NFs) that have been extracted and utilized or expected to be used for special applications. The diameter of NFs ranges between a few to a few hundred nanometers. Methods to arrange synthetic NFs assembly in yarns or pads forms have been examined. High throughput productions, versatility of various thermoplastics, and less environmental pollution are the advantages of the methods of extraction, which seems to make it as an economical process. It can also be used for the polymers that are difficult to be converted to NFs by electrospinning. The process is challenging and scientifically fascinating to attract the investigators. There are many more polymers to be considered, and there are many more envisioned applications that have to be practiced in the future. A theoretical base is needed for the evaluation of the effects of polymer flow parameters on the extracted NFs properties.
