HONEYCOMB-KONTRUKSJON AV TERMOSTRUKTURELT KOMPOSITTMATERIALE SAMT FREMSTILLING DERAV |
摘要 |
A honeycomb structure made of a high-temperature structural composite material comprising a fibrous reinforcement texture is produced from a three-dimensional fibrous texture formed by stacked two-dimensional layers (40) connected together by means of fibres passing through the layers. Staggered cuts in the form of slits (42) are formed through the layers, throughout the entire thickness of the texture, and the cut texture is stretched (drawn) in the direction not parallel to the cuts (42) but parallel to the layers (40) in order to form cavities (46) whose walls are constituted by the lips of the cuts (42). The cut texture, held in the stretched state, is densified by the material which makes up the matrix. <IMAGE> |
