Electrical Properties of Carbon Fiber Support Systems [PDF]
Nucl.Instrum.Meth.A550:127-138,2005, 2005 Carbon fiber support structures have become common elements of detector designs for high energy physics experiments. Carbon fiber has many mechanical advantages but it is also characterized by high conductivity, particularly at high frequency, with associated design issues.

Poly(ionic liquid)-Derived Carbon with Site-Specific N-Doping and Biphasic Heterojunction for Enhanced CO2 Capture and Sensing [PDF]
Angewandte Chemie International Edition, Volume56, Issue26, June
19, 2017,Pages 7557-7563, 2018 CO2 capture is a pressing global environmental issue that drives scientists to develop creative strategies for tackling this challenge. The concept in this contribution is to produce site specific nitrogen doping in microporous carbon fibers. It creates a carbon/carbon heterojunction by using poly(ionic liquid) (PIL) as soft activation agent that ...

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.

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.

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)

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.

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.

Assembly-Dependent Interfacial Property of Carbon Nanotube Fibers with Epoxy and Its Enhancement via Generalized Surface Sizing [PDF]
Advanced Engineering Materials 18(5), 839-845 (2016), 2015 In building up composite structures using carbon nanotube (CNT) fibers, the fiber-to-matrix interfacial shear strength (IFSS) is one of the most important issues. Originating from the assembly characteristics of CNT fiber, the IFSS strongly depends on the fiber's twisting level and densification level.
