METHOD FOR MAKING A STRUCTURAL PART OF A COMPOSITE MATERIAL HAVING A CALIBRATED THICKNESS AND STRUCTURAL PART THUS OBTAINED

摘要

The invention relates to a solution for controlling the thickness of a finished structural composite part (1) when precise tolerances must be respected for the quality of the assembly and in order to facilitate the assembling operations of said part. In order to implement the method of the present invention, an additional layer of plies of a non structural composite material, or calibrating plies (105), is applied on the structural plies (2) of the structural part at least in an area where the thickness must be maintained within narrow tolerances and, after curing the composite material, the calibrating plies (105) are machined in order to obtain a finished part having the desired thickness. The thickness of the applied calibrating plies is determined based on the possible thickness of the structural plies (2) while taking into account the manufacturing dispersion, so that the machining operation of the calibrating plies does not affect the structural plies.
