Brief description of embodiments of a curved profile in the composite material from a preform for a straight line of layers of fibers

摘要

The method involves stacking a set of plies (24, 26) on a deformable mandrel (22), where a curved profile comprises the plies having fibers oriented at preset degrees relative to longitudinal direction. The mandrel and the plies are wound on a bending tool along a rotation axis. The plies sandwiched between the mandrel and the bending tool, are bent in a single-phase. The plies are heated during bending in a deformation zone at temperature on the order of 70 degrees Celsius. The bent plies are polymerized.
