Abstract: A method of manufacturing an aircraft window frame, the frame having a first surface that has at least first and second faces extending all around the frame and connected by a curved junction zone, the frame being made of a composite material that includes fibers embedded in a resin matrix. The method includes steps of: assembling fiber layers and at least one reinforcement situated at the level of the junction zone and having first and second peripheral edges; consolidating or polymerizing of the assembly; and removing the frame from the mold. During the step of assembling, a barrier layer is positioned between the reinforcement and the first surface to cover the reinforcement and to form a barrier limiting propagation of resin in the direction of the first surface. A window frame obtained by using that method is provided as well as an aircraft including the frame.
