    Abstract: A bone-repair composite includes a core and a sheath. The core is a first primary unit including a combination of a first set of yarns coated with an apatite calcium phosphate mineral layer. The first set of yarns being made from a first group of one ore more polymers. The sheath is a second primary unit which can be either polymer or including a combination of a second set of yarns or one or more polymer coatings. The second set of yarns being made from a second group of one or more polymers, wherein the composite is made by covering the core with the sheath, and the composite is compression molded to allow the sheath to bond to the core. The bone-repair composite has a bending modulus comparable to that of a mammalian bone, such that the ratio of the core to the sheath is provided to maximize the mechanical strength of the bone-repair composite to mimic the mammalian bone. Furthermore, a method for making a bone repair synthetic composite comprising the steps of: treating a polymer fiber with a surface modifying chemical, wherein the polymer fiber is a natural polymer or a synthetic polymer; coating the polymer fiber with a mineral layer; and forming a primary structure with at least one of the mineral coated polymers or at least one of the polymer fibers.
