First(1) and second(2) components of fiber composite are placed on a supporting surface(11) and a fiber preform(4) is arranged between them. A first tool(6) with a matrix supply channel(12) is positioned on the two components to form a first airtight chamber(21). A second tool(8) with a suction channel(14) placed on the two components forms a second airtight chamber(22) with an opening to the suction channel. Pressure is reduced between the two components by vacuum application and a matrix fluid fed into the preform via the first chamber(21). Curing of the matrix in the preform is at elevated temperature and under pressure. Meltable yarns incorporated in the fiber preform(4) are heated by the incoming matrix and dissolve into the latter to form a plasticizer. The tools(6,8) are positioned on opposite sides of the two components(1,2) and are sealed off from the latter. The two tools may be combined to form a single tool. An air permeable membrane(10), which is impermeable to the matrix material, is arranged between the preform(4) and the opening(14) to the suction channel. |
