Abstract
A process for manufacturing porous tubes made from carbon-carbon composite material by winding over a mandrel a non-woven sheet, made from a carbon fiber precursor, followed by compression and hot stabilisation of the assembly, with impregnation of the compressed sheet by a resin, followed by a thermal carbonisation treatment of the resin. Tubes are obtained having high permeability, small pore diameter and an inner surface of low rugosity. The tubes produced ar particularly suitable for the manufacture of filtration elements and of filtering membrane supports.
