This study focuses on some mechanical properties resulted from the tensile testing of a set of green composites with a Dammarbased matrix and reinforcement material of silk, flax, cotton and hemp fabrics. To be precise, we have ascertained the characteristic curve, the resistance to and the elongation at fraction, as well as the modulus of elasticity for each set of samples from these composites and for a set of bioresin samples. With the help of an Electronic Scanning Microscope we captured images of the breaking section while on the basis of the EDS analysis we found the chemical composition of a bioresin sample. In order to justify the use of such materials in various fields of activity we compared the elastic and resistance properties of the composites we obtained to other existent composites.
