Impregnation system and method for impregnating a textile fabric for composite components

A method for impregnating a textile layer (1) with a matrix (2) to form a textile fabric (3) for composite components, the textile layer (1) being a unidirectional layer or a multi-axial layer, the method comprising the following steps:

• a) providing an impregnation module comprising a first and a second endless belt loop (4, 5) each running over deflection rollers (7) at respective deflection areas of the endless belt loops (4, 5), and wherein the endless belt loops (4, 5) each have surfaces (6) mutually facing each other;
• b) applying the matrix (2) onto the textile layer (1) and carrying and guiding the matrix (2) and the textile layer (1) between the mutually facing surfaces of the endless belt loops (4, 5);
• c) impregnating the textile layer (1) with the matrix (2) to form the textile fabric (3) in between the endless belt loops (4, 5) in the impregnation module by applying contact pressure perpendicularly in a Y-direction onto the textile layer (1) and the matrix (2) using a wrap angle of the endless belt loops (4, 5) over at least one further roller (8) arranged within the first or the second endless belt loop (4, 5) while the textile layer (1) and matrix (2) are running over the at least one further roller (8);
• and
• d) controlling the contact pressure onto the textile layer (1) and the matrix (2) by varying tension of the endless belt loops (4, 5) and by adjusting the deflection rollers (7) and the at least one further roller (8) independently from each other in the Y-direction of the mutually facing surfaces (6) to vary the wrap angle of the endless belt loops (4, 5) on the at least one further roller (8).
