    The present work discusses an improved process for the manufacture of fibre metal laminates. Fibre metal laminates are super composite materials combining several properties of fibre and metal layers that constitute them and having potential applications in engineering industry and general purpose industrial applications. Literature information available for preparation of fibre metal laminate are expensive and require huge investment for laminate preparation. The present work provides a simple, cost effective and widely adaptable process for the manufacture of fibre-metal laminates. Here, the metal surface is roughened with grit blasting for obtaining strong bond between metal and fibre cloth adhesive layers(Prepreg) as against the regular chemical pre-treatment process. Also, the prepreg layers are prepared in-house using RTM process. The thus prepared prepreg layers and the pre-treated metal layers are bonded together by a combination of heat( in a regular thermal over) and pressure ( obtained by closed mould process). Mechanical properties evaluated show acceptable properties for the prepared laminates.
