We have been developing a composite of OCP/apatite crystal and collagen, which is tough and strong. In our previous study, it was demonstrated that long crystals improved the load-bearing properties of the composite and the flexural behavior depended on the texture of the composite. Here, it was hypothesized that pressing of the wet-composite would promote unifying of collagen fibers and therefore further improve the mechanical properties. Three-point bending tests were used to estimate the mechanical properties of the OCP/apatite-collagen composites. The pressing of the wet composite was effective in increasing the flexural strength, nominal toughness and elastic modulus.
