ABSTRACT:
A tangled fibrous material from cut glass fibre bundles, with the cut glass fiber bundler being fed into a compressed air flow and a glass fibre-laden air being deflected into a turbulent eddy flow of varying direction, so that a tangled fibrous material of wadding-like consistency is formed. Through the simultaneous addition of dry polymer-based binder powder, it is possible to obtain a tangled fibrous material as a starting product for a production of glass fibre-reinforced plastic moundings, which can be compressed to a felt. This can be packed as an intermediate or further processed in a heated belt press to glass fibre-reinforced plastic plates.
