In this project, I manufactured polyurethane foam with a certain density using a two-step process. First, I synthesized polyols from vegetable oils by transesterification and epoxidation reactions. Second, I reacted the polyols with isocyanates to produce polyurethane foam. I measured the density, compressive strength, thermal conductivity, and water absorption of the foam samples. I also compared the properties of the foam with those of conventional petroleum-based foam. The results showed that the foam made from vegetable oils had comparable or better performance than the petroleum-based foam, and had the advantages of being biodegradable and renewable.

This project is about the elaboration and mechanical characterization of modified polyurethane foams. Polyurethane foams are widely used in various applications, such as insulation, packaging, and cushioning, due to their low density, high thermal resistance, and good mechanical properties. However, they also have some drawbacks, such as flammability, brittleness, and low biodegradability. Therefore, modifying polyurethane foams with different additives or fillers can improve their performance and functionality. In this project, I synthesized and characterized polyurethane foams modified with nano-silica, lignin, and cellulose nanofibers. I investigated the effects of these modifiers on the morphology, thermal stability, mechanical properties, and biodegradability of the foams. The results showed that the modified foams had enhanced thermal stability, increased stiffness, and improved biodegradability compared to the pure foams. This project demonstrates the potential of using natural

In this project, I developed and characterized filled polyurethane foams for non-lethal projectiles. Non-lethal projectiles are weapons that can neutralize and incapacitate people without causing permanent harm. However, many cases show that they can still cause severe injuries or even death. Therefore, I aimed to control the manufacturing and the properties of the projectile materials to ensure good effectiveness with a lower injury level. I used a homemade pneumatic launcher and a rigid wall to test the dynamic behavior of the foams. I also performed spectroscopy and XRD analysis to examine the microstructure and the chemical composition of the foams. The results showed that the foams had an open-cell morphology and some chemical irregularities. The project was published in the 10th European Symposium on Non-Lethal Weapons in 2019.

In this project, I investigated the mechanical and microstructural properties of polyurethane foams, which are widely used as thermal insulation materials in various applications. I used different techniques, such as scanning electron microscopy, X-ray diffraction, and compression testing, to analyze the morphology, crystallinity, and compressive behavior of the foams. I also studied the effect of different parameters, such as foam density, cell size, and chemical composition, on the mechanical and microstructural properties of the foams. The results of this project provide valuable insights into the structure-property relationships of polyurethane foams and can help optimize their performance and durability.

I am thrilled to present my project focused on the development and characterization of polymer mousses with applications in non-lethal projectiles. This innovative research, detailed in my publication on ResearchGate (Elaboration et caractérisation mécanique des mousses polymères: application aux projectiles non létaux), bridges the gap between material science and practical, safer defense solutions. In this project, I collaborated with industry and academic experts to create advanced polymer foams that balance lightweight properties with high energy absorption capabilities. These materials are tailored for use in non-lethal defense, offering a safer alternative to traditional materials. The research encompasses extensive mechanical characterization, ensuring reliability and effectiveness in real-world applications.
