用于通过TFP工艺生产单层或多层纤维预型件的方法
摘要：
本发明涉及一种通过纤维束(4-16)、利用TFP工艺生产单层或多层纤维预型件的方法，纤维束大致排列为使得其通过力流被定向，并放置在衬垫层(2)上，并通过固定丝(17)连接，以便形成具有所需材料厚度的纤维预型件(1、25)，而不会对衬垫层(2)造成影响。根据本发明，脱离层(3、26)至少在一定的区域施加到衬垫层(2)，且当完成TFP工艺后，将纤维预型件(1、25)引入到固定装置(24)中，其中至少一些固定丝(17)通过供给的热熔化，接着，通过脱离层(3、26)与纤维预型件(1、25)分开的衬垫层(2)与纤维预型件(1、25)脱离。通过根据本发明方法形成的纤维预型件(1、25)具有最佳的纤维结构，而对于实际上任何所需的材料厚度没有裂纹，并注定用于必须承受高机械载荷的承载部件的复合部件的生产。本发明还涉及一种用于纤维预型件(1、25)的生产的衬垫层，以及涉及一种根据本发明的方法形成的纤维预型件(1、25)。
摘要（英）：

The invention relates to a method for producing, in a TFP method, one- or multilayer fibre preforms (1, 25) substantially comprising fibre strands (4-16) which are oriented in the force flux direction, arranged on a support layer (2) and attached by fixing threads (17) in such a way that the fibre preform (1, 25) having almost any thickness and devoid of the unwanted support layer (2) is formed. According to said invention, a separating layer (3,26) is applied to the support layer (2) at least by sections and, according to the TFP method, said fibre preform (1, 25) is introduced into a fixingdevice (24), wherein at least one part of the fixing thread (17) is molten by supplied heat and the support layer (2) separated from the fibre preform (1, 25) by the separating layer (3,26) is removed therefrom. The support layer for producing the fibre preform (1, 25) and said fibre preform (1, 25) formed by the inventive method are also disclosed.
