摘要

Combining waste materials with lightweight sustainable materials in higher-value applications offers an appealing pathway for future materials design. This combines energy savings with recycling which are of great emphasis in today’s energy and resource-intensive world. Notably, incorporation of biomass to metallic materials has not been explored. In this work, a first-time investigation of direct biomass (fallen waste mango leaves) integration into metallic magnesium is explored, resulting in a novel metal + biomass composite possessing minimal compromise in mechanical response (by 7.9%, 12.0%, 10.7%, 11.4%, and 20.5% for CYS, UCS, ductility, specific strength, and work of fracture respectively) and no adverse thermal effects. Accompanied by superior damping response (by 24.0% and 12.9% for attenuation coefficient and damping capacity respectively) and lower weight owing to higher porosity (increase from 0.44% to 1.56%), this represents a potential new class of sustainable materials inviting further exploration and research, alongside the potential of energy savings and further use of existing biomass waste.
