Composite bone plates made of carbon/epoxy prepregs were investigated for obtaining a more uniform strain distribution at the fracture site of human bones through finite element (FE) analysis. The fracture site was modeled by a multilayered structure. One conventional stainless steel bone plate and several composite bone plates were considered for calculating the strain distributions at the fracture site. The average stresses of bones and bone plates were also calculated for the evaluation of the stress-shielding effect. From the results of FE analysis, it was found that the composite bone plate caused an affirmative strain distribution at the fracture site, which stimulated callus generation.
