Preparation and Characterization of Hybrid Composite Laminated Plates with Variation of Sawdust

From past two-three decades there has been a gradual shift from monolithic to composite materials in order to meet the increasing demand for lighter, high performance, environment friendly, corrosion and wear resistant materials. Composite materials are majorly used in massive production like boats, automotive and air craft Industry etc. in order to improve hardness and impact strength. The manufacturing of hybrid composite laminates is difficult to handle by traditional methods and gives size restrictions, wetting, poor surface finish, more number of moulding required for manufacturing. The Hand lay-up chosen as the fabrication technique when product needs smooth finish slight variations in thickness and number of moldings required is less. The moulding made from materials like plastics, wood, clay, plaster or plywood depending on the availability. Hand lay-up technique has been adopted to manufacture the hybrid composite laminated plate (sawdust with 1%, 2% and 3% variation) and impact strength and hardness is to be calculated.
