抄録

In order to clarify the tensile and fatigue behaviors of fiber-reinforced composite, four kinds of eutectic Al–Al<sub>3</sub>Ni materials with different inter-fiber spacings were prepard by unidirectional solidification. They were cut out to make five kinds of specimens with different angles between applied stress and fiber orientation. Their tensile and fatigue properties were compared with each other by means of a tensile test at the strain rate of 7.7×1O<sup>−5</sup>s<sup>−1</sup> and a bending fatigue test at the strain cycle of 7 Hz and at stresses from 50 to 150 MPa in air. The results obtained are as follows. (1) The tensile properties strongly depend on the inter-fiber spacing and the fiber orientation. The tensile strength decreases with increasing inter-fiber spacing and angle between applied stress and fiber orientation. (2) The fatigue properties also strongly depend on the inter-fiber spacing and the fiber orientation. The fatigue life increases with decreasing inter-fiber spacing and angle between applied stress and fiber orientation. (3) The fatigue raito (the ratio of fatigue stress to tensile stress) does not so much depend on the inter-fiber spacing and the fiber orientation. (4) Therefore, the fatigue life is suggested to be predicted from the tensile properties of the specimen.
