Development and analysis of eco-friendly multi-functional materials

Abstract

Now a day's automobile industries are developing materials in such a way that, the materials should be light in weight and environmentally friendly with excellent mechanical properties. Flax fiber is a naturally available fiber material own excellent mechanical properties. Two reinforced composites were manufactured. One was a complete flax fiber-reinforced composite, the second one was flax fiber metal laminates (combination of flax fiber and aluminum mesh). The manufacturing process of composite materials is also more important, and it is cost-dependent. The hand lay-up method is one of the manufacturing techniques and the cost is very less as compared to other techniques. Manufactured flax fiber and flax fiber metal laminate reinforced composite materials were tested under experimental tests. The experimental test results of flax fiber and hybrid composite materials were compared with each other. The sound transmission loss of flax fiber-reinforced composite material has 15% higher than flax fiber metal laminate reinforced material at the frequency ranges of (400 Hz). The vibration-damping factor of flax fiber metal laminate has 26% higher than flax fiber-reinforced composite. Electromagnetic radiation absorption of flax fiber metal laminate material has 20 db & 15 db higher than flax fiber-reinforced composite material at frequency ranges of (8.16 GHz &12 GHz). The flexural strength and tensile strength of flax fiber material were higher than flax fiber metal laminate material. Finally, the results of the experimental tests were compared with the simulation results of both flax fiber-reinforced composites and flax fiber metal laminate materials. Except for, vibration-damping factor the remaining properties of flax fiber composite material gave better results than the flax fiber metal laminate.
