Method for making textile preforms from textile half-products

摘要

Numbers of individual textile blanks (4) are assembled in a compaction stage. A highly-compact component (5) is produced, in a shape close to its final form. This is saturated with an adhesive resin. It is hardened at raised temperature under increased pressure. Numbers of individual textile blanks (4) are assembled in a compaction stage. A highly-compact component (5) is produced, in a shape close to its final form. This is saturated with an adhesive resin. It is hardened at raised temperature under increased pressure. The blanks are matched with each other and for the final product geometry. A mold (1) is employed for vacuum compaction, which is carried out in a heating oven or other heating unit. Upper and lower mold dies (2, 3) are used, arranging the preforms between them. Their molding faces (6, 7) match the final geometry of the component produced. Centering pins (8) are included between these faces. All parts of the compaction mold are placed inside a vacuum bag (9). Application of reduced pressure applies pressure to the mold halves. An independent claim is included for the corresponding molding equipment.
