In this paper, we determined some mechanical properties of a new category of green composites, based on tensile tests. More precisely, we selected a set of samples from a new bio-resin based on Dammar and two sets of samples from green-composites with matrix by bio-resin and reinforced with almost compact layers of Typha latifolia or Schoenoplectus lacustris. For these built materials, we obtained the characteristic curve, tensile strength, percentage elongation after fracture and elasticity modulus. In addition, for each sample, we observed the breakage area with an electronic microscope. The roughness profile parameters for a bio-resin specimen were determined. Based on the EDS analysis we obtained the chemical structure of the bio-resin. Finally, based on the properties of these green-composites, we proposed a few applications in civil engineering and medical fields.
