Embodiment Construction

[0062] Figure 1a A schematic diagram of a process step during the production of the fiber composite component 2 according to the invention is shown. The figure shows the process steps during the production of a fiber composite component by the liquid composite molding (LCM) method, wherein a sensor device 1 with a flexible circuit carrier 3 or a sensor module 4 is arranged in the fiber composite component. This process step represents the start of a melt flow (matrix flow) 10 .

[0063] The upper part of the view shown is a top view of the mold 30 (view inside the mold / section of the mold). The lower part is a side view of the die 30 along the cutting axis A-A.

[0064] In addition to the view of the mold 30 , the signal curve 6 of the sensor device 1 or the acceleration detected by the sensor module 4 is also schematically plotted. Normal production noise can be seen from signal curve 6.

Abstract

The invention relates to a method for producing a composite fiber component (2), wherein a sensor apparatus (1) having a flexible circuit carrier (3) and / or a sensor module (4), in particular a micromechanical acceleration sensor module, is integrated in the composite fiber component (2), comprising the steps of: loading a tool (30) for producing the composite fiber component (2) with textile layers and the sensor apparatus; closing, in particular air-tight sealing, of the loaded tool and compressing the textile layers and the sensor apparatus; introducing a liquid matrix (10), in particular a resin, in particular a pure resin, into the sealed tool (30) to produce the composite fiber component (2); detecting, in particular in real time, an acceleration relative to the introducing and / or sealing by means of the sensor apparatus (1) and / or the sensor module (4) of the sensor apparatus (1); deriving and / or evaluating a process parameter of the production method depending on the detected acceleration.

Description

technical field [0001] The invention relates to a production method for a fiber composite component, a correspondingly produced fiber composite component, a testing method for a correspondingly produced fiber composite component, a corresponding computer program and a machine-readable storage medium, and a corresponding device. Background technique [0002] A method for arranging a plurality of micromechanical acceleration sensors on or in a plastic component, in particular a bumper, and a corresponding plastic component, in particular a bumper, are known from WO 2018 / 069066 A1. [0003] In step A of the method, the micromechanical acceleration sensor is fixedly positioned in or on the flexible circuit carrier, wherein the micromechanical acceleration sensor contacts the integrated conductor trace structure of the flexible circuit carrier. [0004] In step B of the method, the micromechanical acceleration sensor and the flexible circuit carrier are at least partially arrange...
