The status and role of carbon-carbon composites in medical applications   Carbon has the best biocompatibility of all materials, and carbon-carbon composites inherit this property, which makes them the best materials for surgical implants used under high stress.2D Carbon carbon was used successfully in the 1980s for artificial joints and as […]

Aviation Brake Disc   With the rapid development of aviation science and technology and industry, the landing speed and quality of the aircraft is increasing, the landing speed of modern advanced aircraft has exceeded 350km/h, the take-off weight has reached 600t, the kinetic energy absorbed by the aircraft of a

Pyrolytic graphite is a new type of carbon material made from hydrocarbons or steam as raw material, which is decomposed at high temperature and precipitated on the surface of substrate. The structure and performance of pyrolytic graphite are directly related to the pyrolysis temperature, where the product of pyrolysis at

Natural graphite is a black or silvery gray shiny mineral. The true density of ideal graphite is 2.26 g/cm³, coal is 1.3-1.9 g/cm³, natural graphite is 2.1-2.25 g/cm³, and diamond is 3.5 g/cm³.   Natural graphite has excellent thermal conductivity, which is between the metals copper and iron. The thermal
