ABSTRACT: Cutting and trimming of CFRP laminates with high dimensional accuracy is highly essential for applications like aerospace industry. Non-conventional machining techniques provide a good solution for this problem in which automation‚ precision and dimensional accuracy can be easily achieved. Among them‚ Abrasive Water Jet cutting proves to be a promising area since there is no possibility of thermal damage to the material. AWJ cutting belongs to the mechanical group of non-conventional techniques

Cashew Tree The cashew tree is evergreen. It grows up to 12 metres high and has a spread of 25 metres. Its extensive root system allows it to tolerate a wide range of moisture levels and soil types‚ although‚ commercial production is advisable only in well-drained‚ sandy loam or red soils. Annual rainfall needs to be at least 889mm (35 inches) and not more than 3048mm (120 inches). Cashew trees are most frequently found in coastal areas. It is exported to countries like Japan and Korea and its domestic

The polymers often used to make this composite material is epoxy‚ polyester‚ vinyl and even nylon. Thus in making CFRP carbon fibre is often combined with polymers such as epoxy to result in a material that has a very high strength-to-weight ratio. Carbon fibre reinforced polymers despite being relative expensive as compared to other traditional metallic materials;

Introduction: Rainwater‚ in most cases‚ is the most pure available source of water‚ something which gives rainwater preference over other available sources of water but more importantly‚ roof drainage pollution is also caused by rainwater. In United States the average amount of rainfall across the country is 35″ and the amount of land that is affected by excess water capable of damaging homes and properties is around 20%. Some of the most common environmental and moisture problems that are faced
