Carbon nanofibers based carbon–carbon composite fibers
Discover Nano, 2023 Textile grade polyacrylonitrile (PAN) was used as a precursor material for carbon fiber preparation. E-beam irradiated polyacrylonitrile grafted carbon nanofibers were dispersed in polyacrylonitrile solution (dissolved in dimethyl formamide).

Mechanical behavior of entangled materials with or without cross-linked fibers [PDF]
, 2013 Entangled materials can be manufactured using fibers made from various materials, such as carbon, glass or steel. The mechanical properties of these low-density materials are linked to their architecture (fiber orientation, number of contacts, etc ...

Wide-Range Tunable Dynamic Property of Carbon Nanotube-Based Fibers [PDF]
Advanced Materials Interfaces 2(10), 1500093 (2015), 2015 Carbon nanotube (CNT) fiber is formed by assembling millions of individual tubes. The assembly feature provides the fiber with rich interface structures and thus various ways of energy dissipation, as reflected by the non-zero loss tangent (>0.028--0.045) at low vibration frequencies.

Epoxy insulated carbon fiber and carbon nanotube fiber microelectrodes
Sensors and Actuators B: Chemical, 2013 Carbon-fiber microelectrodes (CFMEs) are typically constructed from glass capillaries pulled to a fine taper or from a polyimide-coated capillary that is 90 μm in outer diameter. Here, a new fabrication method is developed to insulate carbon-fiber microelectrodes with a thin epoxy coating.

FibeR-CNN: Expanding Mask R-CNN to Improve Image-Based Fiber Analysis [PDF]
Powder Technology, vol. 377, pp. 974-991, 2020 Fiber-shaped materials (e.g. carbon nano tubes) are of great relevance, due to their unique properties but also the health risk they can impose. Unfortunately, image-based analysis of fibers still involves manual annotation, which is a time-consuming and costly process. We therefore propose the use of region-based convolutional neural networks (R-CNNs)

Evaluation of New, Sputtered Carbon SPME Fibers with a Multi-Functional Group Test Mixture
Separations, 2021 We report the first fabrication of sputtered carbon, solid-phase microextraction (SPME) fibers. These fibers have competitive extraction capabilities compared with the commercial carbon wide range (CWR) SPME fiber.

Preparation of Carbon Fiber/Carbon Composites Using Intercalated Carbon Fibers
TANSO, 1992 Carbon fiber/carbon composites were prepared from carbon fibers intercalated with AlCl3 as reinforcements, and coal tar pitch or phenol resin as matrix precursor. A1C13, which is known to have a catalytic effect on the carbonization process, was de-intercalated from carbon fibers during the preparation of composites, i.e.
