CLAIMS
r
1. A method of fabricating aluminium composites comprises:
a) cutting the aluminium bar in to small pieces
b) pre-heating the spent catalyst
c) melting the small pieces of aluminium at a temperature of 650 - 780°c
d) mixing the molten aluminium with the spent catalyst and pouring the melt in to the metal moulds

2. The method of claim 1, wherein the spent catalyst is selected form the group of catalysts used in the petrochemical processing, and preferably selected form the group of zeolite and/or vanadium
3. The method of claim 1, wherein the spent catalyst spent catalyst is pre-heated in a pre-heating furnace for a time period of about 20-80 minutes at a temperature range of about 80-180°c
4. The method of claim 1, wherein the melting of aluminium pieces and mixing the molten aluminium with the spent catalyst is performed by casting techniques, preferably by stir casting
5. An aluminium spent catalyst composite of Claim 1, comprising aluminium with spent catalysts of the petrochemical processing as the reinforcing agents.
6. The aluminium spent catalyst composite of claim5, having a hardness value of about 60- 84 HRB
7. The aluminium spent catalyst composite of claimS, having a tensile strength of about
60- 85 MPa and yield strength of about 30- 40 MPa
8. The aluminium spent catalyst composite of claim5, having a wear loss of about
0.27 - 0.67 gm and Co-efficient of friction value of about 0.7 - 0.31
