Abstract:
A method for manufacturing a curved part made of a stack of plies of continuous fibers in a thermoplastic polymer matrix. The part having at least one in-plane curved ply in one of the flanges, where the fibers are aligned with the curvature. The fiber placement parameters are determined to obtain welding of the fibers on a pre-deposited ply without diffusion of segments of the polymer's molecular chains through the interface between the fibers and the pre-deposited ply. An in-plane curved flat blank is produced by automated fiber placement using the parameters. The blank comprises at least one ply where fibers are aligned with the curvature and having an overall porosity content lower than 1%. The blank heated to a temperature greater than the melting temperature of the polymer is hot stamped and consolidated to provide the curved composite part with continuous fiber reinforcement having at least two flanges.

Claim (Index 1):
A method for manufacturing a part made of a stack of plies of continuous fibers in a thermoplastic polymer matrix, said part having at least two flanges and being curved, said part comprising at least one in-plane curved ply in one flange where the fibers are aligned with a curvature, the method comprising steps of:\n determining automated fiber placement parameters to obtain a welding of the fibers on a pre-deposited ply without diffusion of segments of molecular chains of a polymer through an interface between the fibers and the pre-deposited ply, the automated fiber placement parameters comprise a heating temperature and a deposition velocity of a thermoplastic polymer impregnated fibers; producing an in-plane curved flat blank by an automated fiber placement using the automated fiber placement parameters, said in-plane curved flat blank comprising at least one ply where fibers are aligned with the curvature and having an overall porosity content lower than 1%; heating said in-plane curved flat blank to a temperature greater than a melting temperature of the thermoplastic polymer making up the thermoplastic polymer matrix; and hot stamping and consolidating the heated in-plane curved flat blank between a stamping punch and a die to provide a curved composite part with continuous fiber reinforcement comprising at least two flanges.
