Problems solved by technology

One solution is to overlap the edges of these adjacent boards, but this results in additional thickness in the area between the stringers which provides no other benefit and adds undesired extra weight

Abstract

A system and method for splicing multiple plies of material together during the construction of a stringer sheet. A first ply layer is laid onto a portion of a surface of a tool having a contour whichdefines a stringer, and the first ply layer is pressed down such that an edge of the first ply layer is located on the contour. A second ply layer is laid onto an adjacent portion of the surface, andthe second ply layer is pressed down such that the edge of the second ply layer is located on the contour and overlaps the edge of the first ply layer. This process may be repeated for additional plylayers. The system may include an end-effector having a dispenser of the plies of material and a roller for pressing the plies, and a movement mechanism for moving the end-effector over the tool.

Description

technical field [0001] The present invention relates to systems and methods for fabricating composite panel structures, and more particularly, embodiments relate to systems and methods for splicing together multiple ply layers of material during construction of stringer panels, stringer panels For example in the fuselage and wings of an aircraft or in other body parts of a vehicle. Background technique [0002] Stringers are longitudinal members used to strengthen panels, such as the skin in panels used in aircraft fuselages and wings. The function of the stringers is to divide the skin into different sections, which allows the skin to flex safely, controls circumferential damage to the skin and provides stiffness against airframe bending loads. In one implementation, each stringer is constructed as distinct pieces that are attached to the skin using fasteners, welding, or bonding. In another implementation, multiple stringers are built in stringer panels or "plate stringe...
