The effect of hydrogen bond on the thermal and mechanical properties of furan epoxy resins: Molecular dynamics simulation study

open access: yesPolymer Testing, 2021
The hydrogen bonds (H-bonds) are employed for the thermal and mechanical property enhancement of epoxy networks; however, the formation and evolution of H-bonds, especially in emerging bio-based furan epoxy, cannot be deeply understood at the atomic ...

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.

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.

Reconstruction of the Microstructure of Cyanate Ester Resin by Using Prepared Cyanate Ester Resin Nanoparticles and Analysis of the Curing Kinetics Using the Avrami Equation of Phase Change

open access: yesApplied Sciences, 2019
Bisphenol A dicyanate (BADCy) resin nanoparticles were synthesized by precipitation polymerization and used to modulate the microstructure of the BADCy resin matrix. A microscopic mechanism model was used to characterize the curing process of BADCy resin

Carbon nanofibers based carbon–carbon composite fibers

open access: yesDiscover Nano, 2023
AbstractTextile grade polyacrylonitrile (PAN) was used as a precursor material for carbon fiber preparation. E-beam irradiated polyacrylonitrile grafted carbon nanofibers were dispersed in polyacrylonitrile solution (dissolved in dimethyl formamide).

Electrical conductivity improvement of aeronautical carbon fiber reinforced polyepoxy composites by insertion of carbon nanotubes [PDF]

open access: yes, 2012
An increase and homogenization of electrical conductivity is essential in epoxy carbon fiber laminar aeronautical composites. Dynamic conductivity measurements have shown a very poor transversal conductivity.

Carbon Fibers [PDF]

open access: yes, 2015
Remarkably, truly novel structures are still being found for materials made of a single element: carbon. Perhaps there is a ‘revolution’ in carbon-only materials. Indeed, recently, two Nobel prizes were awarded for new forms of carbon: for fullerenes in 1996, and for graphene in 2010.
