Abstract
A reinforcing body and a method for its manufacturing. The reinforcing body has at least one reinforcing bar. Each reinforcing bar has a core with a peripheral surface at which a rib structure with at least one rib and at least one depression is provided. The core is formed by at least one first fiber strand embedded in a core matrix. For creating the at least one rib at least one second fiber strand is embedded into a rib matrix, wherein the at least one second fiber strand and the rib matrix are separated by at least one depression in a direction parallel to a longitudinal center axis of the reinforcing bar, such that the at least one second fiber strand is separated into fiber strand sections. The at least one first and the at least one second fiber strand have fibers of different materials.
