Rezumat:
         Lucrarea isi propune sa analizeze doua din cele mai importante proprietati fizico-mecanice ale brichetelor lemnoase, realizate din biomasa lemnoasa sub forma de aschii obtinute de la masina de rindeluit la grosime. Studiul densitatii brichetelor - ca proprietate fizica si al rezistentei la compresiune perpendiculara - ca proprietate mecanica este impus de faptul ca aceste doua caracteristici exprima atat gradul de comprimare al aschiilor, cat si compactarea acestora. Experimentele efectuate pe doua specii lemnoase - molid si fag - au permis si stabilirea influentei densitatii lemnului asupra densitatii brichetelor si a rezistentei la compresiune.

Cuvinte cheie: brichete din lemn, aschii tehnologice, biomasa lemnoasa, densitate, rezistenta la compresiune.
