MACHINE FOR LAYING STRIPS FOR THE PRODUCTION OF A LAMINATE STRUCTURE OF COMPOSITE MATERIAL ON A COMPLEX CONTOUR LAYING FORM AND METHOD FOR MANUFACTURING SUCH A LAMINATE STRUCTURE

摘要

Description of a method and a machine for applying strips allowing the manufacture of construction elements with a laminated structure from strips of composite material. For the production of construction elements, the strips of material are deposited by the strip laying machine on the complex laying surface of a laying form along natural laying paths for which there are no constraints. mechanical. These natural laying paths are defined by a laying path generation program which adapts the strip of strip material to the complex curved surface avoiding any mechanical stress and provides the data for the desired laying path. Natural laying paths are generated as non-machine specific geometrical data. They are then transformed into orders intended for the machine for controlling and adjusting the displacements of the laying head of the machine. In parallel with the translation into machine language, the orientation of the laying head is corrected for its adaptation to the contoured surface of the laying shape. The orders sent to the machine are transmitted as positions to be reached to an adjustment system for adaptation which, taking into account the difference between the set positions and the actual positions, moves the laying head of the machine to bring it at the desired positions in each case.
