Abstract The weldability of aluminium short-fibre reinforced AA6061 alloy (FRM) to AA6061 alloy and to itself using aluminium brazing materials has been investigated. AA4045 and BA03 were selected as brazing materials. When FRM was brazed to AA6061 alloy with AA4045 sheet, a disorder of fibre orientation near the interface was recognized at a brazing temperature above 863 K. Furthermore, the interface became very irregular and porous. The tensile strength achieved was about 100 MPa on brazing below 863 K. On the other hand, BA03 sheet, which has thin AA4045 layers on an AA3003 alloy layer, made the joint strong. The strength was about 200 MPa. BA03 induced little disorder of fibre arrangement and better contact at the interfaces. The BA03/AA6061 alloy interface was more porous than the FRM/BA03 interface and, hence, weaker. FRM/FRM joints with BA03 sheet had good strengths above 200 MPa.
