Hydroxyapatite (HAp) has been used as the implant material in critical field for its similar composition as the bone and its bioactive characters. But it is lack of enough mechanical strength, for example, bending strength and elastic, and it not suitable for biomaterials. Therefore, in order to improvement those characters of HAp, we have been tried that composed for HAp and Tyranno fiber changed for Tyranno fiber containing rate. Take into consideration of sintering condition, HAp-Tyranno fiber composite gave the 3-point bending test, and evaluated the several property. This time we used for new sintering method by Hot Press, gained that the more increase sintering temperature, the more increase bending strength rather than former method. And we gained for gentle destructive action called "safety destruction" that the case of Tyranno fiber containing rate was high. We considered that the further result is gained by improvement of sintering condition and consideration to the influence of the boundary between HAp and Tyranno fiber for the condition of high temperature.
