2D carbon carbon composite is with only 2 directions of the fibers. mainly x, y directions in the plane direction. Most of the time, the product is produced by carbon fiber cloths, stick together layer by layer, such as carbon composite boards, carbon composite sheets, carbon composite U, L profiles for heaters…
Different names of carbon carbon composite: CFC, Carbon composite, C/C, carbon fiber composite, carbon carbon composite, carbon reinforced carbon, carbon fiber reinforced carbon, carbon carbon.
Due to the properties of carbon carbon composite, the main application of 2D carbon carbon composite is as bellow:
1). Used on the surface of rigid graphite felt, to protect the rigid felt from incoming gas flow, and it has good insulation property.
2). Used as heater and heating elements. see this: http://www.cfccarbon.com/carbon-composite/heater-heating-elements.html
3). Used as U, L profiles to protest the corners parts of furnace. http://www.cfccarbon.com/carbon-composite/carbon-composite-u-l-profile.html
It has many other applications, due to its low cost, good insulation properties, big size plates…
Carbon-carbon composite features:
(1) Physical properties: After high temperature treatment, the carbon composite has higher carbon content, >99%, the density is low, the mechanical properties are good. Due to good characteristic of high melting point of carbon, high temperature resistance, corrosion resistance and thermal shock performance, the carbon composite is resistant to acid, alkali and salt.
(2) Mechanical properties: carbon composite has good mechanical properties of the strength and elastic modulus, good wear and tear resistance.
(3) high-temperature stability: The room temperature strength of carbon composite can keep up to 2500 ℃, is not sensitive to the thermal stress, and the ablation resistance performance is good.
(4) Comprehensive performance evaluation: carbon composite has good strength and elastic modulus at room temperature; less production processes of carbon composite material can save materials and manufacturing costs, and its more safety and reliability.
Special Properties of carbon carbon composite: High Acid-resisting and alkali-resisting properties; Low density compared to metals; High temperature, cold-resistant, tensile strength is 7-9times than Steel; very good thermal shock resistance…
