silicon carbon composites based on natural

Frontiers

Carbon black (CB) filled butadiene (BR) (Cis-1,4-polybutadiene) and natural (NR) (Cis-1,4-polyisoprene) rubber compounds containing CB in 60–100 per hundred (phr) proportions were investigated for their pressure/time-dependent electrical conductivity. Due to their high deformability, the percolation thresholds for CB–BR and CB-NR compounds were functions of pressures (compression loads

FAQs

Silicon carbide, often referred to by its chemical formula, SiC, is a synthetically produced crystalline compound consisting of silicon and carbon. Due to its exceptional abrasive properties, SiC was the first synthetic abrasive to be produced and has been in use since the late 19th century, in applications ranging from sandpaper to grinding wheels and cutting tools.

COMPOSITE MATERIALS AND STRUCTURES

Carbon-carbon composites are the most important class of ceramic matrix composites that can withstand temperatures as high as 3000 0 C. They consist of carbon fibres distributed in a carbon matrix. They are prepared by pyrolysis of polymer impregnated carbon fibre fabrics and preforms under pressure or by chemical vapour deposition of carbon or graphite.
