ENTANGLED CARBON-FIBER NONWOVEN PRODUCTION METHOD AND ASSEMBLY AND THREE-DIMENSIONAL-COMPONENT NONWOVEN PRODUCTION METHOD

摘要

An entangled carbon-fiber non-woven production method for producing an entangled carbon-fiber non-woven fabric from carbon fibers up to a fiber length of 100 mm, with the following steps: supplying carbon fibers; loosening/combing apart and aerodynamically isolating the carbon fibers; aerodynamically calming the isolated carbon fibers; introducing the calmed and isolated carbon fibers into a vertically arranged air shaft (1), wherein the carbon fibers are introduced at the upper end (12) of the air shaft (1); mixing the carbon fibers within the air shaft (1) in a contactless manner by air whirling by means of a plurality of individual air flows; aerodynamically depositing the carbon fibers onto a moving mold or deposit surface (2) arranged below the air shaft (1), wherein the aerodynamic deposition is performed by means of suctioning below the mold or the deposit surface (2), wherein the air flows are varied and/or adjusted in the direction and/or intensity thereof and the air flows are produced and varied by means of one or more rotating and horizontally arranged air nozzles (14). The invention further relates to an entangled carbon-fiber non-woven production device, to a three-dimensional-component non-woven production method, and to a non-woven fabric
