Broadband Supercontinuum Generation in PCF, HNLF and ZBLAN Fiber with a Carbon-Nanotube-based Passively Mode-locked Erbium-doped Fiber Laser [PDF]

open access: yes1. Proc. SPIE 10516, 2.Proc. SPIE 10516, 3. pp.2993-2995, 2020
We demonstrate the broadband supercontinuum (SC) generation in photonic crystal fiber (PCF), highly nonlinear fiber (HNLF) and ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF) fiber with a passively mode-locked erbium-doped fiber laser (EDFL). The passively mode-locked EDFL incorporates a CNT-based saturable absorber and has achieved a pulse width of 620 fs with a ...

Potentials of Polyacrylonitrile Substitution by Lignin for Continuous Manufactured Lignin/Polyacrylonitrile-Blend-Based Carbon Fibers

open access: yesFibers
While carbon fibers (CFs) are still the most attractive reinforcement material for lightweight structures, they are mostly manufactured using crude oil-based process chains.

Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]

open access: yes, 2019
Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.

Mechanical behavior of entangled fibers and entangled cross-linked fibers during compression [PDF]

open access: yes, 2009
Entangled fibrous materials have been manufactured from different fibers: metallic fibers, glass fibers, and carbon fibers. Specimens have been produced with and without cross links between fibers. Cross-links have been achieved using epoxy spraying. The

Influence of the carbonization temperature on the properties of carbon fibers based on technical softwood kraft lignin blends

open access: yesCarbon Trends, 2021
Lignin is an interesting renewable resource for carbon fibers. In this work we investigate the usage of unpurified softwood kraft lignin Indulin AT for melt-spinning of lignin-fibers and the properties of resulting lignin and carbon fibers. Indulin AT is

Processing of carbon-fiber-reinforced Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 bulk metallic glass composites [PDF]

open access: yes, 2001
Carbon-fiber-reinforced bulk metallic glass composites are produced by infiltrating liquid Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 into carbon fiber bundles with diameter of the individual fiber of 5 mum.

Strong Fiber from Uniaxial Fullerene Supramolecules Aligned with Carbon Nanotubes [PDF]

open access: yes, 2023
Carbon nanotube (CNT) wires approach copper's specific conductivity and surpass carbon fiber's strength, with further improvement anticipated with greater aspect ratios and incorporation of dopants with long-range structural order. Fullerenes assemble into multitudes of process-dependent supramolecular crystals and, while initially insulating, they ...

The Recycling of Carbon Components and the Reuse of Carbon Fibers for Concrete Reinforcements

open access: yesApplied Sciences, 2023
Carbon fiber reinforced plastics are increasingly used in all areas of industry. With the increasing number of components and semi-finished products, more and more new carbon fibers will be produced.

Alcohol decomposition on basic/acid lignin-derived submicron diameter carbon fibers [PDF]

open access: yes, 2018
The use of lignin, the second most abundant polymer in nature, along with a simple and versatile technique, electrospinning, represents an advantageous and promising approach for the preparation of carbon fibers.
