Mechanical behaviour and characterization of reinforced CNSL composite material

Abstract

Abstract The natural fibers are cheap and easily available in India. Therefore they play an important role in automobile applications. Also, increase the environmental effect. In this research work, the composite materials are made from natural materials as a hybrid polymer matrix composite. The different materials like coconut fiber, flax and glass fibers which were made from the natural material were prepared in the form of a matrix and appropriate resins were mixed to have proper bonding of the material. Also, on the other hand, the use of cashew nut shell liquid (CNSL) in the position of phenol, synthetically derived substance conversion. This CNSL is available in India and is cheap. The utilization of this cashew nut shell liquid is 100% free from chemical products are pure. So when this CNSL is added with the flax and glass fibers gives excellent strength to the material. The fiber is also treated with a NaOH solution was used at 5%, 15% and 20% and the duration time of treatment was increased to 72 h in order to increase the strength of the composite material. Taguchi L9 method was used for different concentration of NaOH, the volume of fiber with respect to soaking time. To find the best percentage of the mechanical test flexure strength was carried out with the help of changing the concentration at the time of treatment with NaOH. Orthogonal array called Taguchi L9 was carried out to test/design of random experiments procedure for better simplification and further the statistical a test called Analysis of Variance was carried out to test the level of significance of flexural strength of the composite material made from natural fibers.
