In Brief:
To initiate a database on material properties of typical laminations used in prosthetic limb sockets, the authors subjected samples of common prosthetic laminations to tensile and bending tests. Eight varieties of lay-up materials (fibers) were each laminated separately with one of three common resins (matrix), resulting in 24 combinations of fiber/resin laminates. In addition to composition, the bending responses of various carbon fiber laminations were measured to evaluate the role of layer placement on bending strength. Results showed that formulations grouped into three categories based on mechanical strengths. These data provide a preliminary database of material strengths of typical laminations and suggest the utility of minimum standards for prosthetic laminations.
