Experimental investigations on wear and drilling delamination characteristics of fibre reinforced hybrid polymer composite

Abstract

Composite materials is one of the fastest growing area in the field of Materials Engineering and Technology Composites offer unique combination of desirable properties by combining two or more dissimilar materials There are several classes of composite materials available and used in industries like marine aircraft and automobile engineering Among these composites fibre reinforced composites have been used in many industries due to their excellent mechanical properties compared to particulate and laminar composites The fibre reinforced composites are easy to fabricate exhibit lightweight and high stiffness with excellent wear resistance In fibre reinforced composites natural materials are being considered as reinforcing medium due to its easy availability better performance and eco friendly in nature However natural fibres alone do not meet the required strength of the developed composites To overcome this difficulty synthetic fibres have been used to complement the natural fibres to improve the strength of the hybrid composites By introducing synthetic materials in the developed composite it results in reduction of adhesion strength fibre pull out during machining To overcome the above issue one more material namely Nano clay is added to obtain the desired adhesive strength between the matrix and reinforcement materials In the present investigation the Natural fibres Sisal and Jute Synthetic fibre E Glass Nano clay and Polymer materials Epoxy resin have been used for fabricating the composites The chopped form of 10 vol sisal and jute fibres newline
