DRAPING DEVICE FOR PRODUCING A THREE-DIMENSIONAL PREFORM OF FIBROUS MATERIAL

摘要

The invention relates to a draping device (13) for producing a three-dimensional preform (5) of fibrous material, comprising a female mould (14) reproducing the three-dimensional shape of the preform (5), and one or more mould cores (15) for draping and/or fixing, which are designed to cooperate with the female mould (14). The invention substantially consists in that different mould cores (15) on their surface (16) facing the preform (5), and/or different portions of this surface (16) of at least one mould core (15), have different surface roughnesses and/or roughness values; and or the surface (17) of the female mould (14) facing the preform (5) has portions with a different surface roughness and/or different roughness values.
