The Ampelodesmos mauritanicus plant, Mauritanian grass or also called 'Diss', is a perennial abundant plant on the Mediterranean contour, having attractive characteristics for ecofriendly materials. This work aims to highlight the potential of the Diss fibers elements by assessing their use as reinforcement for polymer matrices (bio-composite). So, untreated and treated Diss fibers by chemical (soda, silane and acetic acid) and thermal treatment have been manually extracted and characterized to evaluate their surface condition as well as their chemical composition, their mechanical properties and their thermal stability. The obtained results have shown many advantages look promising for such an application, especially the fact that the Diss fiber bundles has small diameter (89 ± 22 μm), a rough surface with the presence of thorns, a low density of 0.93 g/cm3, and a tensile strength that can reach 270 MPa. Furthermore, all the treatments adopted have shown improvements regarding the fibrillation of fiber bundles (could reach −40% for the diameter), their surface state, their thermal stability and their mechanical behavior (could reach +60% for Young's modulus and +15% for tensile stress).

“…This perennial plant belongs to the family Poaceae rich in fibers (Damerdji 2012). Recently, this plant attracted the attention of researchers and particularly to be used as a reinforcement for cement composites (Merzoud and Habita 2008) (Achour, Ghomari, and Belayachi 2017), and polymer composites (Bourahli 2014) (Sarasini et al 2019). In terms of extraction methods, chemical composition, treatments, mechanical and thermal behavior, Diss fibers have been subject to several studies in the literature (Merzoud and Habita 2008) (Bourahli and Osmani 2013) (Achour, Ghomari, and Belayachi 2017) (Sarasini et al 2019) (Nouri et al 2019).…”

Diss fibers, also called Ampelodesmos mauritanicus, are one of the least studied fibers in the literature. Indeed, the rare studies discussed have focused on mechanical and physicochemical properties. The present work deals with hygrothermal characterization and the effect of treatments on their behavior. So, untreated and treated Diss fibers with chemical treat-ments (alkaline, silane, and acetic acid) and heat treatment were character-ized by absorption tests by water immersion and others by water vapor adsorption and desorption (Proumid-SPS). The results found have shown that these fibers presented a type II sorption isotherm with hysteresis where their saturation point could reach up to 40% of their dry mass. However, the treatments carried out seem to be able to reduce their hydro-philic nature especially after heat, silane, and acetic acid treatments. The adsorption kinetics, on the other hand, also seem to be positively influenced by these treatments, especially after the chemical treatments.

“…Compared with traditional synthetic fibers (glass, carbon, aramid, etc. ), natural fibers, especially plant fibers, show many appealing characteristics as low cost, low density, abundantly available, renewability, high strength, and elasticity modulus, thus demonstrating great potential in the new generation of sustainable composites . Many researchers attempted to prepare more economical and environmentally friendly polymer composites by adding various natural fibers into the polymer matrices.…”

We successfully added bamboo and glass fibers into bisphenol A-aniline based benzoxazine (BA-a) resin by hotpressing method. In order to improve the interfacial adhesion between bamboo fibers and the matrix, bamboo fibers were pretreated in 6 wt% NaOH solutions for 12 h. The results showed alkali-treatment had a positive effect on mechanical properties of the composites at both room and elevated temperatures (60 C, 110 C, 160 C, and 210 C). Due to the incorporation of glass fibers, the bamboo/glass reinforcedpolybenzoxazine hybrid composites exhibited highest strength and modulus among all samples and had high residual mechanical properties at elevated temperatures (residual mechanical properties refers to the ratio of strength and modulus of the composites at elevated temperatures to that measured at room temperature). The fractured surface morphologies of the composites were observed by scanning electron microscope. The results showed with the increase of temperature, the debonding and fiber pull-out became apparent, and the matrix softening could be clearly observed at 210 C. In addition, thermal and thermomechanical properties of neat benzoxazine and the composites were also investigated through thermogravimetric analysis and dynamic mechanical analyzer, respectively.
