Abstract: Biocomposites (natural fiber composites) from local and renewable resources offer significant sustainability; industrial ecology, eco-efficiency, and green chemistry are guiding the development of the next generation of materials, products, and processes. Considerable growth has been seen in the use of biocomposites in the domestic sector, building materials, aerospace industry, circuit boards, and automotive applications over the past decade, but application in other sectors until now has been limited. Nevertheless, with suitable development, the potential exists for biocomposites to enter new markets and thus stimulate an increase in demand even in the field of Fiber Metal Laminates . Many types of natural fibers have been investigated with polymer matrices to produce composite materials that are competitive with synthetic fiber composites which require special attention. Fibre Metal Laminate (FML) is largely used in the manufacture of aircrafts. The commercially available FMLs, GLARE, CARALL (CArbon Reinforced ALuminium Laminate) and ARALL make use of Aluminium metal. Other FMLs that are under study by researchers make use of metals such as Titanium and Magnesium based alloys. Owing to the high cost of carbon Fibre and the necessity for environment friendly alternatives, in the present work, a portion of carbon is replaced by natural fibre materials in CARALL and CARMAL (CArbon Reinforced MAgnesium Laminate). To the knowledge an attempt has not been made before in the field of FMLs the use of Natural fiber in place of Glass fiber and Carbon fiber In recent an attempt has been made by using a natural fibers as a laminating material by which a number of Natural materials like Fiber or flakes can be used. An attempt is also reported with jute as CArbon- Jute Reinforced ALuminium Laminate and CArbon-Jute Reinforced MAgnesium Laminate are named as CAJRALL and CAJRMAL. Both these laminates are made by hand layup technique and then compressed in a compression moulding machine.
