A structural system comprising: a stringer having a first side and a second side, the stringer comprising a first section and a second section, wherein the first section is a discontinuous section, wherein the second section is positioned relative to the first section such that the second section extends away from the first section in a first direction substantially perpendicular to the first section, wherein the second section meets a first portion of the first section at a first location of the second section and a second portion of the first section at a second location of the second section, wherein the stringer has at the first location a first curved shape and at the second location a second curved shape, wherein, at the first side of the stringer, the first section is configured for attachment to a surface of a base charge, and the second section is not in contact with the surface of the base charge; the base charge comprising a first surface and a second surface, wherein the first surface is attached to the first section at the first side of the stringer, wherein the first surface of the base charge is not in contact with the second section at the first side of the stringer; a skin attached to the second surface of the base charge; a channel on the first side and in the second section and extending along a length of the stringer, the channel having a transverse shape; and a noodle comprising a composite structure and placed in the channel and attaching the second section of the stringer to the first surface of the base charge, wherein the composite structure comprises composite layers having fibers arranged in different orientations with respect to an axis through the stringer, wherein the axis is substantially perpendicular to the first direction, wherein the composite layers are laid up in a configuration comprising groups of layers, each group of layers comprising a first, a second and a third layer, wherein the first layer comprises fibers arranged at an angle of about zero degrees with respect to the axis, and the second and the third layer comprise fibers arranged at an angle selected from a range between about 45 degrees and about 50 degrees with respect to the axis, wherein the composite layers are configured such that the shape of the noodle substantially conforms to the transverse shape of the channel after the noodle has been cured, wherein the group of layers does not include any layers having fibers arranged at an angle of about 90 degrees with respect to the axis. a stringer having a first side and a second side, the stringer comprising a first section and a second section, wherein the first section is a discontinuous section, wherein the second section is positioned relative to the first section such that the second section extends away from the first section in a first direction substantially perpendicular to the first section, wherein the second section meets a first portion of the first section at a first location of the second section and a second portion of the first section at a second location of the second section, wherein the stringer has at the first location a first curved shape and at the second location a second curved shape, wherein, at the first side of the stringer, the first section is configured for attachment to a surface of a base charge, and the second section is not in contact with the surface of the base charge; the base charge comprising a first surface and a second surface, wherein the first surface is attached to the first section at the first side of the stringer, wherein the first surface of the base charge is not in contact with the second section at the first side of the stringer; a skin attached to the second surface of the base charge; a channel on the first side and in the second section and extending along a length of the stringer, the channel having a transverse shape; and a noodle comprising a composite structure and placed in the channel and attaching the second section of the stringer to the first surface of the base charge, wherein the composite structure comprises composite layers having fibers arranged in different orientations with respect to an axis through the stringer, wherein the axis is substantially perpendicular to the first direction, wherein the composite layers are laid up in a configuration comprising groups of layers, each group of layers comprising a first, a second and a third layer, wherein the first layer comprises fibers arranged at an angle of about zero degrees with respect to the axis, and the second and the third layer comprise fibers arranged at an angle selected from a range between about 45 degrees and about 50 degrees with respect to the axis, wherein the composite layers are configured such that the shape of the noodle substantially conforms to the transverse shape of the channel after the noodle has been cured, wherein the group of layers does not include any layers having fibers arranged at an angle of about 90 degrees with respect to the axis.
