Epoxy insulated carbon fiber and carbon nanotube fiber microelectrodes

open access: yesSensors 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.

Wide-Range Tunable Dynamic Property of Carbon Nanotube-Based Fibers [PDF]

open access: yesAdvanced 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]

open access: yesPowder 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)

Degradation Behavior of Thermal Stabilized Polyacrylonitrile Fibers

open access: yesCailiao gongcheng, 2017
In the temperature range of 300-800℃, 40%-50% of the mass lost during the processing of polyacrylonitrile based carbon fiber (PANCF). Understanding the degradation behavior will be valuable in understanding the formation mechanism of pseudo-graphite ...

Preparation of Carbon Fiber/Carbon Composites Using Intercalated Carbon Fibers

open access: yesTANSO, 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.

Assembly-Dependent Interfacial Property of Carbon Nanotube Fibers with Epoxy and Its Enhancement via Generalized Surface Sizing [PDF]

open access: yesAdvanced 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.

One-Step Densification of Carbon/Carbon Composites Impregnated with Pyrolysis Fuel Oil-Derived Mesophase Binder Pitches

open access: yesC, 2020
Carbon/carbon (C/C) composites are conventionally manufactured by liquid-phase impregnation (LPI), in which the binder pitches and phenolic resins are impregnated into the composites, and by chemical vapor infiltration (CVI).

Effect of water-soluble thermoplastic polyimide sizing agent on interfacial properties of domestic high strength and high modulus carbon fiber reinforced composites

open access: yesCailiao gongcheng, 2023
The water-soluble thermoplastic polyimide sizing agent was synthesized from bisphe- nol A-type diether diether dianhydride (BPADA), m-phenylenediamine and 4, 4′-(1, 3-phenylenedioxy) dianiline (TPE-R).
