  • Patent number: 11780180
    Abstract: A fiber composite laying method for producing a fiber composite scrim for forming a fiber composite component. The method includes supplying a reinforcement fiber band to a laying head, laying and compacting the supplied reinforcement fiber band on a laying surface at an average compaction pressure by a compaction roller, and detecting a local compaction pressure on the laid reinforcement fiber band by pressure sensors on the compaction roller.
    Type: Grant

  • Patent number: 11551346
    Abstract: A computer system is provided for processing ultrasonic data of an ultrasonic probe applied to an area of an aircraft component that includes carbon fiber reinforced polymer. C-scan data is obtained and a preliminary mesh is defined over the C-scan data by taking into account the underlying structural or mechanical characteristics of the analyzed component. The mesh is further refined and data gathered for each mesh cell. A heat map is generated based on the mesh.

  • Patent number: 11426953
    Abstract: A fiber composite laying device for producing a fiber composite scrim for forming a fiber composite component has a laying head which is designed or configured to continuously supply a reinforcement fiber band, a compaction roller which is designed or configured to receive the supplied reinforcement fiber band, lay the band on a laying surface and press the band onto the laying surface at an average compaction pressure, and pressure sensors which are arranged on the compaction roller and are designed or configured to detect a local compaction pressure on the laid reinforcement fiber band.

  • Patent number: 10359278
    Abstract: The present disclosure refers to a method for measuring thickness in any type of carbon fiber component, even in components having parts with different thickness and integrating at least a second material. The method includes measuring with the maximum and minimum real thickness of the component, and measuring with ultrasonic equipment the time that the ultrasound takes to propagate across the component part with maximum and with minimum thickness, calculating a thickness correction value, and calculating an ultrasound test speed from said thickness correction value, said measured times, and said measured maximum and minimum real thickness. Then, the total thickness of each of the parts of the component are measured, using ultrasounds with the same calculated ultrasound test speed, and the thickness correction value is applied to each of the measuring total thickness of each part, to determine a corrected carbon fiber thickness for each part.
