Wear rates and friction coefficients were measured for a PAN fibre-CVI matrix carbon-carbon composite with different fibre orientations at the wear faces. A constant torque dynamometer operating at rotational speeds in the range 1800-8000rpm (3.5-15.7ms -1 average linear sliding velocity) was used in a ring on ring configuration sliding wear test. Fibre orientations parallel to the wear...
Microstructural studies using X-ray diffraction, SEM, and optical microscopy were made of wear debris from carbon–carbon composite aircraft brakes produced under different simulated braking operations. Under simulated cold taxiing conditions, particulate wear debris comprising a disordered carbon phase containing fibre fragments is formed. The disordered phase is produced mainly by shear deformation...
Plasma facing materials for the next fusion reactor devices will have severe problems such as thermal shock fracture, surface erosion and injection of sputtering particles to plasma caused by charged particle fluxes and very high heat shocks. A joining material, in which a carbon fiber reinforced carbon composite was joined to oxygen-free copper by inserting a molybdenum plate and some metallic films...
The increasing availability of powerful computers has resulted in a rapid increase in computer simulations of adsorption processes in carbonaceous adsorbents. These simulations, which are based on assumed intermolecular potential functions applied to an adsorbate in a model carbon pore, provide insights into adsorption in carbon micropores that are not available from other methods. In this paper...
The effect of addition of the iron graphite intercalation compound (GIC-FeCl 3 ) to coal tar pitch, used as a carbon precursor, on the porosity development in the resulting steam activated chars, was studied. Different conditions of chars preparation have been considered. Benzene (298 K), nitrogen (77 K), carbon dioxide (298 K) and water (298 K) sorption measurements were taken as basis...
