Investigation and optimization of machining parameters during machining of GFRP composite using Annova Taugchi Techniques

In recent years, mankind has established that the protection of the environment becomes a vital part in the discovery of any engineering applications. Several engineering applications in the areas of agriculture, forestry, and energy industries have developed several composite materials in place of other materials for their effectiveness. This work focuses on synthesis of a composite material and the matrix material used in the research work was epoxy resin. Glass fibres were used as the reinforcement material for the preparation of the hybrid epoxy-based composite. The epoxy used in this work is LB011 epoxy resin lapox B_11. The hardener used is Triethylenetetramine (TETA). The composite laminates are prepared by varying the weight proportion of the glass fibres and tested for its mechanical properties. The composite laminate with high tensile strength is selected for the investigation of machining properties of the composite laminate. Optimization of machining parameters is carried out by a novel analysis called Desirability Function Analysis (DFA), which is an optimal tool considered for the problems with multi objective optimization function.
