Embodiment Construction

[0027] The drawings and the following description provide specific illustrative embodiments of the present disclosure. Accordingly, it should be understood that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of and are included within the scope of the disclosure. Furthermore, any examples described herein are intended to assist in an understanding of the principles of the present disclosure and are to be construed as not to be limited to these specifically recited examples and conditions. Therefore, the present disclosure is not limited to the specific embodiments or examples described below, but is limited by the claims.

[0028] Composite parts, such as carbon fiber reinforced polymer (CFRP) parts, are initially laid up in layers that are collectively referred to as preforms. The individual fibers within each layer of the preform are aligned parallel to each other, but the d...

Abstract

The invention relates to the manufacture of a curved composite preform for an aircraft by an assembly line. Systems and methods are provided for manufacturing a curved preform (146) of fiber reinforced material (221). The method comprises: laying (804) at least one ply (220) onto a carrier (210) of flexible material at a lamination station (130); loading (806) a carrier (210) onto the rail system (110); routing (808) the carrier (210) to a particular layer-by-layer (PBP) forming station (140) at the rail system (110); separating (810) the at least one ply (220) from the carrier (210); and manufacturing (812) the at least one ply (220) into a preform (146) via a particular PBP forming station (140).

Description

technical field [0001] The present disclosure relates to the field of manufacturing, and in particular, to the manufacture of aircraft. Background technique [0002] The mechanical structure of an aircraft is called the airframe. The airframe is made of discrete components such as stringers, spars, skins, and frames, which when assembled together define the shape of the aircraft. A single aircraft may be fabricated from a number of such components, all or some of which may be fabricated as composite parts. For example, an aircraft may utilize a large number of curved or curved frames to reinforce its fuselage. Ideally, the frames are manufactured at a rate sufficient to meet the desired assembly timing for the desired production rate of the aircraft, otherwise manufacture of the aircraft may be undesirably delayed. [0003] The abstract of US 9 731 899 B1 describes the provision of systems and methods for controlling flexible rails. One embodiment is a system for conveyi...
