摘要
The process according to the invention makes it possible to obtain a semifinished product in the form of a strip having a homogeneous microstructure and a green density at least equal to 55% of the theoretical density, this semifinished product being able to be densified at a temperature below the temperatures usually required. According to this process, a slip of the powder intended to form the matrix is cast, in strip form, by means of a shoe (11), onto fibres (8) which are arranged on a plate (6) and stretched between two combs (7), the slip and the surface of the fibres exhibiting chemical affinity.
