---|---|
Abstract | A process for the preparation of a light weight ceramic composite material for use in bullet proof panels/shelters comprising: (a) preparing a blend of alumina (2.5% approx.) and other additives (4.5% approx.) as herein described in the powder form, (b) compacting said powder blend in a die to obtain green compact, (c) sintering said green compact to obtain dense tiles, (d) bonding said sintered ceramic tiles to the sheets of impregnated fabric by covering under pressure, (e) overwrapping said sheets with a spall cover, followed by pressing/curing o obtain said ceramic composite material. |
Full Text | DESCRIPTION (COMPLETE) OCR NOT PREPARE DUE TO PRINT PROBLEM CLAIM: 1. A process for the preparation of a light weight ceramic composite material for use in bullet proof panels/shelters comprising : a) preparing a blend of alumina (2.5% approx.) and other additives (4.5% approx.) as herein described in the powder form, b) compacting said powder blend in a die to obtain green compact, c) sintering said green compact to obtain dense tiles, d) bonding said sintered ceramic tiles to the sheets of impregnated fabric by covering under pressure, e) overwrapping said sheets with a spall cover, followed by pressing/curing to obtain said ceramic composite material. 2. A process as claimed in claim 1 wherein said powder blend consists of oxides, borides, carbides and/or nitrides of aluminium. 3. A process as claimed in claim 1 wherein said tiles at step d are bonded to the backing material using epoxy resin. 4. A process as claimed in claim 1 wherein said fabric comprises fibre glass sheets from preimpregnated fabric. 5. A process as claimed in claim 1 wherein said step of sintering is carried out at a temperature of 1600 to 1950°C. 6. A process for the preparation of a light weight ceramic composite material substantially as herein described and illustrated in the examples. |
