Experimental Study of Mechanical Properties and Drilling Properties of Glass Fibre Composite

Abstract

The use of glass fiber polymer composite materials are on the rise due to their special properties like high specific strength and stiffness, excellent corrosion resistant, high damping, low thermal expansion high factor toughness. Majorly it is used in the fields of aerospace and automobiles especially in defense use. Though, manufacturing of these of these laminates are easy to their required shapes but obtaining a drilling in the laminate poses difficulty, due to its anisotropic non homogeneous nature. The rate of rejection at the final stage due to non selection of right machining drill parameters which makes the researchers to find the optimal solution effectively. Sometimes rejection rate accounts up-to 60% and hole drilling being one of the last operations creates many problems, mainly delamination stress concentration and improper hole quality with impounding higher cost factor. This paper presents an investigation on aspects of various mechanical properties and drilling of Glass fibre Mat Composite. Drilling experiments was conducted to study the delamination factor and hole quality on GFRP composites. Also the study carried out for Tensile Strength, Hardness and Flexural Strength of Glass Fibre Composite.
