| Research Abstract |
We have been developing an osteoconductive composite with both strength and toughness, using octacalcium phosphate(OCP)/apatite crystal and type I collagen. Composite was consolidated at room temperature or 40℃under dry and wet conditions. Mechanical property of the consolidated blocks was measured by 3-point bending tests. It was found that the consolidation temperature and wetness were critical to increase the strength and toughness. While, Youngs' modulus was increased by dry consolidation at 40℃.
