The invention relates to a method for manufacturing a window frame (118.1) of an aircraft, said frame comprising a first surface (S1) having a curved coupling region (133) extending over the entire contour of the frame (118.1), the region being made of a composite material and comprising a stack of fibrous layers (132, 134, 134 ') and at least one reinforcement (136) located at the coupling region (133). The manufacturing method comprises an assembly step of assembling the different fibrous layers (132, 134, 134 ') and the reinforcement (136), during which step a barrier layer (138) is positioned between the reinforcement (136) and the first surface (S1) to form a barrier that limits diffusion of the resin in a direction toward the first surface (S1). The invention also relates to a window frame obtained using this method and to an aircraft comprising said frame.

    本发明涉及一种飞行器的机窗框架(118.1)的制造方法,所述框架包括第一表面(S1),该第一表面具有在框架(118.1)的整个轮廓上延伸的弯曲联接区域(133),该区域由复合材料制成,并包括一叠纤维层(132、134、134')和位于联接区域(133)处的至少一个加固件(136)。该制造方法包括组装不同的纤维层(132、134、134')和加固件(136)的组装步骤,在此步骤期间,屏障层(138)定位在加固件(136)和第一表面(S1)之间以形成限制树脂沿朝第一表面(S1)的方向扩散的屏障。本发明还涉及使用该方法获得的机窗框架以及包括所述框架的飞行器。
