Patent ID: 10124568

Abstract:
A method of manufacturing a curved profile from a rectilinear preform of pre-impregnated fiber plies. The method includes stacking plies on a deformable mandrel and winding the deformable mandrel and the stacked plies on a bending tool along a rotation axis, the profile comprising a stack of N plies. At least one first section of the profile is arranged along a plane perpendicular to the axis of rotation and at least one second section is arranged in a plane parallel to the axis. The method includes the steps of stacking the N plies of fibers on the deformable mandrel, bending in a single step the N plies sandwiched between the deformable mandrel and the bending tool and polymerizing the bent N plies. The curved profile comprises M plies with fibers oriented at A° relative to a longitudinal direction and M+/−5% plies with fibers oriented at −A°.
