Auxetic materials, characterized by a negative Poisson's ratio, exhibit the unique property of becoming thicker perpendicular to the applied force when stretched. This unusual behavior makes them highly suitable for applications requiring enhanced energy absorption and impact resistance. Auxetic polyurethane foams, in particular, are an emerging class of materials with significant potential in various industrial applications, especially for anti-shock utilization.
In this project, I focused on the development and enhancement of auxetic polyurethane foams. The primary objective was to improve and create new formulations that result in auxetic polyurethane foams with a negative Poisson's ratio. Through this work, I aimed to develop foams that exhibit superior mechanical properties and are particularly effective in absorbing shocks and impacts.
I employed various characterization techniques, including spectroscopic and microscopic methods, to analyze the structure and performance of the newly formulated auxetic foams. The comprehensive analysis allowed us to understand the material behavior under different conditions and optimize the formulations for industrial applications.
This project contributes to the advancement of high-performance, durable auxetic polyurethane foams, offering significant benefits for applications requiring high energy absorption and impact resistance.
