ABSTRACT:
The invention relates to a sintered highly porous body comprising at least one layer that is made of a material, which can be sintered and which contains fibers. The aim of the invention is to provide a body of the aforementioned type with improved burn-off properties and values for the flame adherence. To this end, the fibers used are curved on one and/or both sides and they have a principal axis that is shorter than approximately 1 mm and a secondary axis that is shorter than approximately 200 μm, whereby the principal axis is longer than the secondary axis. The invention also relates to a method for producing the sintered porous bodies and to the use thereof.
