Hot Pressing Carbon

Graphite with Carbon infusion

Carbon-graphite with resin infusions.

Regarding to the way of sponginess reducing (disposal), carbon-graphites are devided into:

  1. Carbon-graphite with synthetic resin infusion.
  2. Carbon-graphites with metal infusions.

In both cases infusion reduce sponginess, increase modulus of elongation, hardness (not very much), TCLE (thermal coefficient of linear expansion), thermal conductivity.
