Abstract
Process and machine for the manufacture of a composite material reinforced with a three-dimensional continuous fiber structure. A fiber bundle is positioned in direction Z. A plate fitted with fiber guides holds the fibers apart. Fiber layers arranged alternately according to directions X and Y are formed between the fibers of the bundle. The fiber 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 fibers of a same fabric to layer p(X) and q(Y) corresponding to the desired structure. The fibers undergo impregnation during displacement of the combs.
