METHOD FOR PRODUCING A WEB-LIKE FIBROUS STRUCTURE

摘要

The invention relates to a method for producing a web-like fibrous structure by, in a first step, forming a first partial fibrous structure (21) and then, in a second method step, forming a second partial fibrous structure (22) while at the same time joining it to the first partial fibrous structure using joining fibres (5) when forming the first partial fibrous structure and when joining the two partial fibrous structures. The invention furthermore relates to a covering material made from fibre-reinforced plastic, in which the plastic is reinforced with a web-like fibrous structure according to the invention. The invention also relates to a panel structure in sandwich form, which comprises at least one core layer with layers of covering material which bear against the top side and underside and are joined to the core layer, in which the covering material is a covering material according to the invention.
