Creep tests were caried out on an aluminum matrix composite unidirectionally reinforced with continuous alumina fibers to examine the effects of fiber orientation on the creep behavior under the off-axis tensile load. Creep curve of the specimen, which was stressed at angles of O゜, 5゜ and 45゜ to the fiber axis respectively, was almost occupied by the normal primary creep except near fracture. On the other hand, the creep curve of the 90゜ specimen was dominated by the tertiary creep from the early stage in the stress range studied.　 The creep strength of off-axis specimens was closely related to the off-axis tensile strength obtained from the tensile tests. Therefore, the creep strength of off-axis specimens was able to be reasonably understood by the theory for the off-axis tensile strength of fiber-reinforced composite, such as the maximum stress theory or Tsai-Hill theory.
