Abstract

A system (1) and a method for liquid composite moulding are presented. The system (1) comprises a first rigid tool part (3) onto which a semi-finished fiber material (11) is positioned. Furthermore, the system comprises a first vacuum foil (5), a second vacuum foil (7) and granulated material (9). The first vacuum foil (5) is arrangeable in such a way on the first rigid tool part (3) that a first gastight chamber (19) is provided between the first vacuum foil (5) and the first rigid tool part (3). A first port (13) is provided at the first gastight chamber (19) in such a way that a semi-finished fiber material (11) positioned between the first rigid tool part (3) and the first vacuum foil (5) is infusible with a matrix material (23) via the first port (13). Between the first vacuum foil (5) and the second vacuum foil (7) a second gastight chamber (21) is provided in which the granulated material (9) is arranged. Furthermore, a second port (15) is provided at the second gastight chamber (21) for applying a negative pressure (p1) to the second gastight chamber (21). Therein, the granulated material (9) is adapted for forming a second rigid tool part (25) when negative pressure (p1) is applied to the second port (15). I.e. the first vacuum foil (5), the second vacuum foil (7) and the granulated material (9) function similarly to a vacuum mattress and may be stiffened and collapsed.
