1. A reinforcing body (10), comprising:
at least one reinforcing bar (11) that extends in an axial direction along a longitudinal center axis (A) that has a core (17) and a rib structure (18) arranged at a peripheral surface (20) of the core (17) having at least one rib (19) and at least one depression (22) that each extend transversely to the axial direction, wherein the at least one rib (19) comprises one of a single helical rib having a plurality of axially spaced-apart rib portions and a plurality of separate, spaced-apart ribs,
wherein the core (17) comprises at least one first fiber strand (14) of first fibers (26) embedded in a core matrix (27), wherein the rib structure (18) comprises at least one second fiber strand (25) of second fibers (28) embedded in a rib matrix (29) divided into a plurality of separate and axially spaced-apart fiber strand sections (25a) formed by removal of at least a portion of the at least one second fiber strand (25), wherein each of the plurality of fiber strand sections extends between opposite axial ends,
wherein the fiber strand sections (25a) of the at least one second fiber strand (25) that are directly adjacent in the axial direction are separate and axially spaced from each other by the at least one transversely extending depression (22) formed by the removal of the at least a portion of the at least one second fiber strand (25) and each fiber strand section (25a) is arranged in a rib (19) or a rib portion of the at least one rib (19),
wherein the fiber strand sections (25a) of the at least one second fiber strand (25) extend in the axial direction at least in straight extending sections of the reinforcing bar (11),
wherein the second fibers (28) of the at least one second fiber strand (25) are made of a fiber material that is different from a fiber material of the first fibers (26) and the fiber material of the second fibers (28) is less alkali-resistant than the fiber material of the first fibers (26), and
wherein the at least one rib (19) has a lateral dimension extending in a lateral direction perpendicular to the axial direction measured from the peripheral surface (20) of the core to an outer peripheral extent of the at least one rib (19), and the at least one transversely extending depression (22) has a lateral dimension extending from the peripheral surface (20) of the core (17) to an outer peripheral extent of the at least one transversely extending depression of from 0 to 50% of the lateral dimension of the at least one rib (19) such that adjacent ribs or rib portions of the at least one rib (19) are axially spaced-apart from one another by the at least one transversely extending depression.
