The adding influence of natural nano powder to unsaturated polyester as a green composite for prosthetic socket application

For the last few decades, both economic and ecological interests have resulted in more intensive use of natural materials for the creation of new composites, and issues such as recyclability and environmental safety can become increasingly important for the introduction of new materials and products. This work is focusing on the development of a green composite of unsaturated polyester resin (UP) reinforced by a cost-effective and eco-friendly natural Nano powder of Pineapple leaves with different volume fraction i.e. (3, 6, and 9) vol. % as Biomaterials for a prosthetic socket application, and investigate the effect of natural Nano powder of Pineapple leaves in Tensile, Flexural, Impact, and Hardness of unsaturated polyester (UP). Results revealed that flexural modulus values, impact strength, and hardness properties had been enhanced by increasing the volume fraction of natural Nano powders, while the results revealed that the tensile strength, tensile modulus, elongation percentage, and flexural strength decrease with increasing filler content.
