Abstract

본 발명은 금속 피복된 알루미나 단섬유를 보강시킨 알루미늄재 복합재료를 제조하는 방법에 관한 것으로써, 기지금속 또는 강화재에 비해 상대적으로 취약한 피복층과 Al2O3섬유간의 계면결합력을 증가시켜 인장 강도 및 연신율이 우수한 Al 재 복합재를 제조하는데, 그 목적이 있다. 본 발명은 금속피복된 알루미나(Al2O3) 섬유로 예비성형체를 제조한 다음, 이 예비성형체에 알루미늄(Al)재용탕을 가압, 함침시켜 복합하여 알루미늄재 복합재료를 제조하는 방법에 있어서, 예비성형에 앞서, 상기 금속 피복된 알루미나 섬유를 10-5Torr이상의 진공하에서 300-1400℃의 온도로 열처리하는 고강도 알루미늄재 복합재료의 제조방법을 그 요지로 한다.The present invention relates to a method for manufacturing an aluminum composite material reinforced with alumina short fibers coated with metal, and increases the interfacial bonding force between Al 2 O 3 fiber and the coating layer, which is relatively weaker than that of a base metal or reinforcing material, to increase tensile strength and An object of the present invention is to prepare an Al ash composite having excellent elongation. The present invention provides a method of manufacturing an aluminum composite material by preparing a preform with a metal-coated alumina (Al 2 O 3 ) fiber, and then pressing and impregnating an aluminum (Al) ash melt on the preform. Prior to preforming, the method of producing a high-strength aluminum composite material is heat-treated to a temperature of 300-1400 ° C. under vacuum of 10 −5 Torr or more.
