This paper summarises the results obtained from the characterization assays from century plant (Agave americana L.), determining the chemical composition of different parts of the plant. Fibres were obtained by means of a mechanical device, specifically designed and built for Agave americana leaves processing. Obtained fibres were subjected to thermogravimetric analysis and infrared spectra, and their...
This paper presents the results of research on the effect of hydrated calcium sulfate (phosphogypsum) on the mechanical properties of composite based on aluminum powder. The phosphogypsum used is a by-product obtained in the phosphate fertilizers industry, e.g., at the Gdańskie Zakłady Fosforowe “Fosfory.” The amount of phosphogypsum produced in Poland must be reduced due to the high costs of its...
