Preparation of fine steel wire-reinforced aluminum composite by the powder rolling

Abstract

Most of fiber reinforced metal are made by hot press or infiltration method. it is quite difficult to produce long products by either of the methods. If the powder rolling method can be used to make reinforced metal with continuous fiber, the range of the use of fiber reinforced products can be broadened and the economical benifit will be enhanced. In this study, the authors attempted to prepare fine wire reinforced aluminum plate by using the powder rolling method. Mechanical properties of the plate were investigated and the suitability of this process was appraised. The results obtained in this study can be summarized as follows: (1) It is possible to prepare the reinforced plate by using powder rolling method. (2) The tensile strength of the plate increased with increasing of the volume fraction of the wire and its value is reached to 300MPa at about 7% in volume fraction. (3) The Young's modulus of the plate increased with increasing of volume fraction of the wire and these values agreed with those calculated from the rule of mixing. (4) The density of the plate increased with increasing of the volume fraction of the wire. (5) The heat resistance of the plate is higher than that of the commercial aluminum.
