Abstract

A reinforcing fiber, in particular for fiber composite materials, has a core which is provided with a layer of a pyrolysable binder. A coating of pyrolytic carbon or sugar is provided between the core and the layer fiber strands are provided with reinforcing fibers of this type and fiber strands are coated in this way. Fiber composite materials can be prepared with these reinforcing fibers. Processes for producing reinforcing fibers and composite materials involve coating fiber strands.
