Figure 18.19. Comparison of flexural stress deflection curves of a classical, injection molded PLA bone nail (dashed hne) with that of an isotropic, injection molded PGA/PLA-mixture (dotted line), and with the same mixture after MFC-treatment (fully drawn hne). All three curves are much lower than the one obtained with a confidential PLA mixture after processing by solid state extrusion (top, fully drawn line)... Figure 18.19.
