A technique for making recording microelectrodes containing an ultrafine carbon fibre is described. This technique can be used for single- and multi-barrel microelectrodes. These microelectrodes not only have a very low signal-to-noise ratio comparable with that found in tungsten microelectrodes but are simpler to make.

Polydimethylsiloxane coated carbon fibres for the production of carbon-fibre reinforced carbon
Carbon, 1991Abstract HT-fibres (Grafil XAS12K) were coated with thin layers of polydimethylsiloxane in order to prevent or diminish the adhesion of the phenolic resin to the fibre surfaces. The physical and chemical changes of the polydimethylsiloxane layer at various stages of curing and thermal treatment were studied using contact angle measurements, scanning ...

Accurate Fibre Orientation Measurement for Carbon Fibre Surfaces
Pattern Recognition, 2013Carbon- and glass fibre materials exhibit challenging optical properties, in particular highly specular reflectivity. State of the art vision-based sensor systems use diffuse light setups to suppress specular reflections and apply texture analysis to obtain fibre orientations for surface patches.We investigate the reflection behaviour of fibrous ...

Deformation Mechanisms of Carbon Fibres and Carbon Fibre Composites
2016It is demonstrated how Raman spectroscopy can be employed to characterise both the structure and deformation of carbon fibres and also stress transfer from a polymer matrix to carbon fibres in a composite. It is shown that well-defined Raman spectra can be obtained from individual carbon fibres and this can be employed to both follow the carbonisation ...

Thermoelectric processing of carbon fibres
Fibre Chemistry, 2000It was found that when an electric current with a density of 45.6·106 A/m2 is passed through a carbon fibre for 15 sec, its temperature increases to 950@deg;C. This causes the total elimination of sorbed moisture, oiling agent, and surface contaminants, and increases the filament strength to 3640 MPa, which is 18% higher than for fibres undergoing “wet”

Histological response to carbon fibre
The Journal of Bone and Joint Surgery. British volume, 1985The soft tissue response to carbon fibre was studied histologically one and a half years after being used to reconstruct the lateral collateral ligament of the human knee. A remarkably consistent pattern was seen in the induced ligament. The basic pattern was a "composite unit", consisting of a core of carbon fibre enveloped in a concentric manner by ...

Carbon fibre, manufactured from a polyacrylonitrile fibre precursor, is used to reinforce plastic in the aircraft industry. When carbon fibre was fed into a hammer mill, only low concentrations of dust of respirable size could be produced and less than 1% of the respirable carbon particles were fibrous. The dust cloud contained a few transparent fibres,

Biocompatibility of carbon fibre and carbon fibre microparticles.
Aktuelle Probleme in Chirurgie und Orthopadie, 1983Carbon fibres are integrated by the organism without causing significant foreign body reaction, but even with normal tissue growth around and encasement of the individual fibres. However, integration of the fibres into the tissue is not as good when the fibres are coated with epoxy-resin.

Tensile Characteristics of Carbon Fibres
Materials Science Forum, 2000In single filament tensile tests with different gauge length, the macromechanical tensile properties of carbon fibres (strength, failure strain and modulus) have been determined. By calculating system compliance, the experimental failure strain and modulus values were converted to the corrected values.
