Applicability of FT-IR Techniques and Goniometry on Characterization of Carbon Fiber Surfaces

open access: yesJournal of Aerospace Technology and Management, 2016
Carbon fibers have been widely used as structural reinforcement in aeronautical composites, because of their exceptional mechanical properties. However, carbon fibers present few polar groups on their surfaces inducing a weak interaction with some ...

Anionic Citrate‐Based 3D‐Printed Scaffolds for Tunable and Sustained Orthobiologic Delivery to Enhance Tissue Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A potent anionic citric acid‐based 3D‐printed scaffold is developed for the sustained and controlled release of orthobiologics to enhance orthopedic therapeutic efficacy. Comprehensive in vivo studies demonstrated effective bone fusion and high safety at a low dose of BMP‐2 delivered by the system, establishing it as a promising platform for safe ...

Topological Insulator Layered Bi2Te3 Based 3D‐Printed Nanocarbon Electrode for Rechargeable Aqueous Ammonium‐Ion Battery

open access: yesAdvanced Functional Materials, EarlyView.
In this work, Bi2Te3 is integrated into a 3D‐printed nanocarbon electrode for NH4+ storage. A rocking‐chair battery with CuHCF as the cathode delivers a high energy density of 134.8 Wh kg−1 and a power density of 1800 W kg−1. The design allows easy recovery of carbon additives, promoting sustainability and recyclability in next‐generation aqueous ...

Investigation of the degradation of pitch-based carbon fibers properties upon insufficient or excess thermal treatment

open access: yesScientific Reports, 2017
To overcome the disadvantages of discontinuous conventional batch extruders, a continuous screw extruder is introduced to manufacture pitch-based carbon fibers. For a carbon fiber preparation process, an oxidation time of 8 h was determined to be optimal

Brominated graphitized carbon fibers [PDF]

open access: yes, 1991
Low cost, high break elongation graphitized carbon fibers having low degree of graphitization are inert to bromine at room or higher temperatures, but are brominated at -7 to 20 C, and then debrominated at ambient.

Wood Reconfiguration Enables Broadband Blackbody in Large‐Area, Modular, Optically Welded Carbon Constructs

open access: yesAdvanced Functional Materials, EarlyView.
Wood‐based broadband blackbody is achieved by reconfiguration of wood with lignin nanoparticles prior carbonization. Neglectable reflectivity from the visible to infrared wavelengths is obtained by combining thin nanostructures originated from the wood cell walls with long‐range microcavities in the wood lumina.

The effect of fiber oxidation on the friction and wear behaviors of short-cut carbon fiber/polyimide composites

open access: yeseXPRESS Polymer Letters, 2007
Pitch-based short-cut carbon fibers were treated by HNO3 oxidation, thereafter the treated (CFN) and untreated carbon fibers (CF) were incorporated into polyimide (PI) matrix to form composites.
