“…During the carbonization process, the oxidized PAN loses about 50% in mass and linearly shrinks 10%. The shrinkage is an important parameter and must be controlled (8) , and for this purpose, an OPFF sample about 0.7m × 0.25m was cut and displaced in a special sample holder that can control the sample shrinkage in two dimensions.…”

Activated carbon fibers (ACF) are known as excellent adsorbent materials due to their fast adsorption rate and easy handling characteristic. The ACF can be manufactured from the polyacrylonitrile fiber, based on an usual carbon fibers (CF) production process accomplished by an additional activation process. The aim of the present work is to describe the production, chemical/morphological characterization and application potentiality of activated carbon fiber felt (ACFF) produced from textile PAN fiber, using a set of homemade equipment. The 5.0 dtex PAN fiber tow with 200 thousand filaments was oxidized and used as raw material for felt production. The oxidized PAN fiber felt (OPFF) was displaced in a special sample holder, carbonized (900 °C) and then activated in CO 2 atmosphere at 1000 °C in an electric tubular furnace. All steps of the process were performed as fast as possible, and characterization was done by 77 K N 2 isotherms, adsorption isotherms in liquid phase, scanning electronic microscope, X-ray diffraction and surface chemistry by Bhoem methodology. The results confirmed the production of essentially microporous (pore < 3.2 nm, centered on 1.2 nm) and 1,300 m 2 g -1 surface area. The ACFF produced have demonstrated a strong potential application as electrode supercapacitor.

“…His work shows both the non-circular cross-sectional area of carbon fibres and the uneven surface structure. A very distinct kidney-shaped cross-section of fibres can be found in Kumar et al and Marcuzzo et al [9,10]. Additional information is found in Chand's 'Review of carbon fibres for composites' [11].…”

The Young's modulus of single carbon fibres, virgin and recycled, is investigated in this study. Single fibre measurements are enhanced in two fields: firstly, the cross-sectional area is calculated by taking individual measurements with a laser diffraction sensor and applying a sinusoidal fit to account for irregular fibre shapes. Secondly, strains during the loading cycle are measured directly by applying fluorescing tracking markers on the fibre and using one-dimensional digital image correlation. Several markers are applied on each side of the fibre to allow for a statistically verified evaluation. To achieve high-resolution images, a step-wise load cycle is applied. The load is increased in steps of 250 MPa until final failure. It is demonstrated that direct strain measurement and enhanced determination of the Young's modulus are possible for carbon fibres. It was further shown that the recycling of the carbon fibre by pyrolysis reduced the Young's modulus by approximately 10% compared to virgin fibres.
