Abstract: Despite the wide range of plants exploited in the world, there remains a vast variety that is not yet
sufficiently studied such as the diss plant. Diss, or Ampelodesmos mauritanicus, is a plant species
of the Poaceae family. This perennial plant is one of the most abundant plant resources on the
Mediterranean contour and along the Atlantic coast in France, but it is little used. In order to
highlight the potential of these plant’s fibers, this work aims to assess the possibility of using them
as a reinforcement for polymer matrices (bio-composite). In this respect, untreated and treated
diss fibers by NaOH treatment, silane treatment, acetic acid treatment and heat treatment have
been characterized to evaluate their surface condition as well as their mechanical and hygric
behaviour by the following methods: Fourier transform infrared spectroscopy (FTIR), scanning
electron microscopy (SEM), X-ray diffractometry (XRD), thermogravimetric analysis (TGA), tensile
tests and moisture / water absorption tests. The results obtained have shown that these fibers
advantages look promising for such an application, especially a rough surface with the presence
of thorns, a low density, and a tensile strength that can reach 270 MPa. Furthermore, all the
treatments adopted have shown improvements regardeng the fibrillation of fiber bundles, their
surface state and their mechanical and hygric behaviour.
