Document Type and Number:
WIPO Patent Application WO2003060218
Kind Code:
A1
Abstract:
The invention relates to a fibrous structure, particularly of glass, comprising at least one layer of randomly-distributed filament yarns and at least one reinforcing textile layer such as a layer of chopped strands. The different layers in the structure are interconnected using a mechanical means, such as stitching or needle punching, and/or a chemical means such as a binder. The inventive structure can be produced in a continuous or discontinuous manner. Said structure possesses good permeability and good deformability when it is used to produce a composite material.
