    摘要: This invention provides a method for producing a structural component, particularly in the aerospace sector. An unhardened prepreg fabric (6) is formed from a composite fibre material, hardenable at a first hardening temperature, into a predetermined shape. The unhardened prepreg fabric (6) is then connected to at least one hardening part (12, 13) of a composite fibre material partially hardened at a second hardening temperature for holding the unhardened prepreg fabric (6) in the predetermined shape, wherein the second hardening temperature is lower than the first hardening temperature. In a further method step the unhardened prepreg fabric (6) connected to the at least one holding part (12, 13) is hardened at the first hardening temperature to form the structural component. The idea on which this invention is based consists in replacing expensive tools of special steel previously used for holding dimensionally unstable prepreg fabrics with at least one holding part (12, 13) of composite fibre materials, wherein the at least one holding part (12, 13) has a lower hardening temperature than the prepreg fabric (6), and can therefore be produced with a lower cost tool.

    摘要: Disclosed is a method for producing a profiled semifinished fiber composite (FC) product from a semifinished product (2) that is made of dry fiber or prepreg material and is moved through a shaping device (1) in the longitudinal direction (L) of the semifinished product (2). The semifinished product (2) is moved through the shaping device (1) on a support film in the longitudinal direction (L) of the shaping device (1), between the facing shaping contours of tool parts (11a, 12a). The shaping contours of the cross-sections of the tool parts (11a, 12a) continuously change from a cross-sectional contour in the feeding zone to a shaping contour in the discharge zone. Furthermore, the support piece in the drawing-in zone of the shaping device (2) is made to oscillate such that the semifinished product is transformed into a shapeable state as a result of the frictional heat generated between the support piece and the semifinished product. The rate of movement of the semifinished product (2) is regulated in accordance with a temperature of the semifinished product (2). Also disclosed is an apparatus for carrying out said method.

    摘要: The invention relates to a method and to a tool (1, 48) for producing a T-stringer, in particular in air travel and space travel. The method is characterised in that two intermediate strips (3, 4) are superimposed, sections (5, 6) of said intermediate strips (3, 4) being associated with a stringer base (60) that is to be formed, are separated from each other by means of separation films (7, 8) and the sections (14, 15) of the intermediate strips (14, 15) associated with a stringer rod (61) are brought into direct contact, in particular in a material fit. In a further method step, the sections (5, 6) of the intermediate strips (3, 4) associated with the stringer rod (61) that is to be formed are clamped in a clamping device (1). In another method step, the sections (5, 6) that are associated with the stinger base (60) that is to be formed, are folded in the counter direction (28, 29) by means of an unfolding pin (25) and pressed counter to the corresponding pressure surfaces (23, 24) of the clamping device (1) by means of a pressing cylinder (37), such that the sections (5, 6) are aligned exactly. Subsequently, only the folded intermediate strips (3, 4) are hardened in order to form the T-stringer that is to be produced. The invention method has an advantage over known methods for producing T-stringers in that a smaller number of steps are required in order to produce the T-stringer, and said steps could easy be automated.
