| 摘要 |
The carbon or carbonisable fibrous structure (1) comprises a layered tube including an innermost layer (2), an outer layer (3) and at least one intermediate layer (4). The intermediate layer (4) is formed from a material (5) comprising carbon yarn or precursor carbon yarn in the form of a substrate (6) with a pile (7; 10) projecting from at least one side thereof. Preferably, the substrate (6) is woven and has piles (7, 10) projecting from both sides thereof. Preferably also, the pile (7; 10) has been raised from the substrate (6) by fracturing the yarns making up the substrate (6), for example by needling, carding or abrading the substrate (6). A method of manufacturing such a structure (1) is also disclosed. The structure (1), is used in friction products and hollow, heat-resistant structures. |
