摘要

Process and machine for the manufacture of a composite material reinforced with a three dimensional continuous fibre structure. A fibre bundle (18) is positioned in direction Z. A plate (10) fitted with fibre guides holds the fibres apart. Fibre layers arranged alternately according to directions X and Y are formed between the fibres of the bundle. The fibre layers fabrics are carried by combs (40a to 40d) which are displaced in the Z direction and pivoted in order to bring the spacing between the fibres of a same fabric to layer p(X) and q(Y) corresponding to the desired structure. The fibres are undergo impregnation (72) during displacement of the combs.
