Abstract
A method for manufacturing stringers for aircraft, wherein the stringer comprises two semi-stringers, includes steps of placing tows on a flat surface for forming the semi-stringers independently or at the same time, the placement being made by partially overlapping the tows and orientating the tows on the flat surface according to boundaries of the flat surface, the tows covering the boundaries of the flat surface; and cutting the tows so that a shape of the tows corresponds to the shape of the flat surface defined by boundaries of the flat surface.
Claims8
A method for manufacturing stringers for aircraft, the stringers each comprising two semi-stringers, the method comprising the following steps:
- placing tow tapes which are substantially rectangular and include larger sides and smaller sides on a flat surface that has an elongated shape and defines a central line for forming the semi-stringers independently or at the same time, said placing being made by partially overlapping the tow tapes and orientating the tow tapes on the flat surface according to boundaries of the flat surface, the tow tapes covering the boundaries of the flat surface and a whole of the flat surface;
- and
- cutting the tow tapes so that a shape of the tow tapes corresponds to a shape of the flat surface defined by the boundaries of the flat surface;
- joining the cut tow tapes together thus forming a first semi-stringer of the two semi-stringers;
- forming a second semi-stringer of the two semi-stringers via the same process by which the first semi-stringer is formed either independently or at the same time on the flat surface;
- and
- joining each of the two semi-stringers together,
- wherein the tow tapes are oriented so that the larger sides of the tow tapes form an angle between 45° and 90° with respect to the central line of the flat surface.
