The Alfa plant Stipa tenacissima L was harvested in the northeastern region of Morocco near the city of Oujda Fig 1 Alfa fiber contains % of cellulose % of hemicellulose % of lignin and % extractives [27] The diameter of Alfa fiber is in the range of 1 2 mm and a density of g/cm Alfa fibers were cleaned in order to remove
The present work is a comparative study of the impact of different Alfa fiber modifications on fiber properties as well as on polylactic acid PLA composites behaviors A specific process that combines successively mechanical chemical and enzymatic treatments xylanase and pectinase was employed to optimize the performances of Alfa fibers
For Alfa fibers above 7 % the strength capacity decreased while RCS15A sample exhibited a flexural value of % lower than that of control sample RCS0A specimen The strength defect results from the increase in the intra and extra fiber porosity which in turn allow to reduce the specimen compactness
Cherradi et al [7] combined the fibers from alfa plant and sawdust wood into a composite absorber and found that the added alfa fibers improved the porosity and thus increased the absorption

Due to its renewability availability and high cellulose content ≈45% Alfa fibers Stipa tenacissima have been identified as a sustainable source for cellulose microfibers CMF and cellulose nanocrystals CNC production Subjecting raw Alfa fibers to alkali bleaching and sulfuric acid hydrolysis treatments allowed producing CMF and CNC with high yields The
Alpha fibers have been modified by alkali and hydrothermal treatments respectively The bio composites were produced from a mixture of 30% earth and 70% crushed sand 0 4 mm by mass as a

The alfa fibers were obtained after chemical and mechanical treatments of alfa stems with a length between and m and cross section diameter between and mm [13] First the alfa stems are washed with distilled water Fig 1 a and then they are immersed in 10% NaCl liquid for 24 h at 60 °C in order to remove all impurities Fig 1 b
Abstract This experimental study highlights the effect of the geometric form factor λ=length/diameter and the fiber mass fraction on the mechanical behavior of an Alfa/Greenpoxy bio composite The Alfa stalks collected in the Djelfa region in the Algeria highlands were cut into pieces with length of 7 to 10 cm washed and dried for two days at 70 °C Using a knife mill
