New bone substitute material is demanded that has biocompatibility. Other, it is wished that the material is according to go time to decrease material. It was selected to use polybutylene succinate (PBS) -Hydroxyapatite (HAp) composite material. PBS has been a biodegradable resin and excellent ductility. HAp has been a bone formation inducing ability, which would been advance the reproduction of defected bones. However, there also have been our laboratory reports that the strength property of PBS-HAp composite material is lower than that of pure PBS material. Therefore, it is needed that has been kept two advantage while improving strength property. So, it is selected to use glass fiber (GF) for fiber reinforcement. The purpose is study investigate mechanical evaluation that New material design is prepared that has PBS-GF-HAp composite material. We performed the three-point bending test for the specimen to estimate the maximum bending strength and load stroke. As a result, it was recognized that PBS-GF-HAp composite material is obtained high bending strength and toughness by fiber reinforcement. Furthermore, composite material with continuous fiber is obtained higher bending strength than composite material with single fiber because continuous fiber has more bridging effect. Furthermore, PBS-GF composite material doesn't have fiber reinforcement because GF isn't obtained surface treatment by HAp.
