A simple technique for fabricating the metal matrix tubular type composite is described. SiC fiber was used as a reinforcement and was incorporated into the aluminium matrix by squeeze casting technique. The tubular type composite was cut into ring type specimen and tensile-tested at the temperature of 293, 623 and 723 K. The tubular type composite consists of a composite layer and an aluminium layer. The thickness of the composite layer could be controlled by the thickness of the wound SiC fiber layer before casting. The volume fraction of the composite layer was about 40% and did not change with the thickness of the SiC fiber layers prior to the casting. Tensile fracture behavior of the ring type composite changed remarkably with the composite layer thickness. Tensile strength decreased with increasing the testing temperature.
