The process‐induced deformations constitute a severe obstacle to composite part designing and manufacturing. Therefore, in the present work, a method of geometric compensation of those deformations is presented. The compensation process starts with the development of a calculation method which allows to calculate the deformations with the use of Finite Element Method. Linear elastic material model is used in the calculations. Then, the calculated deformations are used to design the compensated geometry of the tool which allows to decrease the deformations of the cured part. The compensation method was verified by compensating and manufacturing a double‐curved fragment of a composite wing leading edge. It appeared that the compensation method allowed to decrease the initial deformation of the structure fragment by approximately 77%. POLYM.
