Calibration body or piece, e.g. for use as length reference, comprises carbon fiber composite material with the composite formed from a porous carbon matrix with which silicon is reacted to form silicon carbide

摘要

Calibration body made from carbon fiber composite material, with the composite material being a porous carbon containing matrix in which the fibers are embedded. Liquid infiltration of silicon into the matrix takes place with the resultant chemical reaction forming silicon carbide with a percentage by volume of up to 60 %. The length of the carbon fibers is a minimum of 3mm.
