The invention relates to a bioresorbable implant (1) for supplementing or replacing heart tissue and/or soft tissue, comprising at least one reinforced fiber/fiber bundle, a fiber structure, or a fiber construct (2) which is made of a first material component and which is embedded into a matrix (3) after being mixed with a second material component. The material of the first material component contains at least one of the elements of the group consisting of silk, chitosan, collagen, polycaprolactone, poly(D,L-lactide), poly(lactid-co-glycolid), polyglycolide, polyurethane, and polypropylene, wherein the second material component is present in a granular or pulverulent form at the point in time in which the material component is mixed with the fibers/fiber bundle, fiber structure, or fiber construct (2). The invention likewise relates to a method for producing such an implant (1).
