New complex product based on fibres and fillers, and method of manufacturing such a new product.

摘要

The present invention relates to a novel composite product which is composed of a fibrocrystalline heterogeneous structure consisting of: on the one hand a plurality of fibers of expanded specific surface area and of hydrophilic character, having a substantial quantity of microfibrils on their surface, and on the other hand crystals of precipitated calcium carbonate (PCC), organized essentially in clusters of granules, the majority of which trap the microfibrils and are joined directly thereto by mechanical bonding.
