发明名称 Method for producing a curved profile made of composite material from a rectilinear preform of fibre layers
摘要 The method involves placing a first portion of a curved section piece in a transverse plane perpendicular to a rotation axis, where a second portion of the piece parallel to the axis comprises one layer of fibers oriented at 0 degree C along length of a Z-shaped rectilinear perform (20). The fiber layers are stacked on a deformable mandrel (22), where the mandrel comprises a neutral fiber (40) placed between last layer of fibers stacked on the second portion and the axis. The fiber layers are bent in a single phase inserted between the mandrel and a bending tool. Bent layers are polymerized. An independent claim is also included for a deformable mandrel.
