Humans on the earth are continuously approaching to become aliens. Firstly the adoption of things by humans which becomes essential because of the mistakes we've made. In order to give indications of nature and to find new technology, we have to play with nature again and again, as a result of which today's situation is not going to be good for us. We have spread our needs without thinking the result. Firstly think very seriously before adoption of any new technology or event, this is very important. Skipping any step in adoption of new technology will have very bad results in future. Different wars whether they are technological and biological leaves bad impact among the society. Recently we have seen the corona crisis, millions of deaths. Till now people have to wear mask and have to change their living pattern, like mask becomes an essential part of the human life. I consider this thing as the first step by humans to be an alien. Our planet also faces the interconnected crises of rapid climate change and biodiversity loss. We have years, not decades, to address these existential threats.

Fiber-reinforced polymer composites (FRPC) consists of fibers that act as a reinforcing agent and a matrix phase to bind the fibers together thereby producing new material with combined properties of each of its constituents. It is a well-known fact that human hair is second highest in strength per unit thickness after spider¿s web. This makes human hair a suitable substitute for some existing expensive materials by fabrication of a new composite material that uses human hair as one of the reinforcing materials. In the present work, we utilize the human hair and the coir fibers in appropriate proportion with polyester resin as a matrix to develop a new natural fiber composite material. All the composite material samples are developed with fiber and resin in the ratio 1:9. The newly developed material is tested for bending strength, impact strength, and water absorption to investigate its mechanical properties.
