Guidelines For The Use Of Silicon Carbide Whiskers

2) The amount of silicon carbide whiskers added to the material is not as high as possible, and there is usually an optimum value. Ordinary ceramics are generally added in an amount of 1-10%. The greater the true density of the matrix material, the lower the amount of silicon carbide whiskers added; the organic composite material is added in an amount of 0.5-3%.
