Abstract
A process for the impregnation of carbon fiber bundles enables the carbon fiber bundles to be impregnated with a curable liquid resin without the impregnated fiber bundles sticking together. The fiber bundles are present in a mechanically generated fluidized bed during the impregnation and are held in the fluidized bed until the resin has been cured or at least dried. A resin-impregnated carbon fiber bundle, a shaped body and an intermediate body for silicization are also provided.
