Abstract

A multi-layer, fiber-reinforced composite orthopedic fixation device having a design selected based on a desired characteristic of the orthopedic fixation device. The design may be selected according to a model of the device, the model defining design constraints, and the design may comprise a pattern of the fiber angle for each layer. The selection of a design may be analyzed using finite element analysis to determine whether the design will comprise the desired characteristic.
