ABSTRACT:
Woven or non-woven fabric, in particular for the manufacture of prepregs especially for the manufacture of structural components in the aviation industry, manufactured of fibers, preferably carbon fibers having an elasticity modulus in excess of 80 000 N/mm.sup.2, preferably of 200 000 N/mm.sup.2 and a specific gravity of preferably 1,5 g/cm.sup.3, and not more than 2,1 g/cm.sup.3, wherein the fibers are composed of mono-filaments, and the fibers and therefore also the fabrics have been pressed flat, preferably calendered. In order to produce a woven or non-woven fabric which is mechanically particularly strong and yet can be manufactured economically, each fiber is composed of at least 2000, preferably 3000 individual mono-filaments (3K=200 tex=200 g/1000 m). The woven or non-woven fabric is preferably used for the manufacture of prepregs and henceforth for lightweight structural components especially for the aviation industry and in particular for overhead luggage compartments.
