Abstract
In this paper, were determined the mechanical properties for Dammar based composite materials. For the begining, were determined the mechanical properties (elasticity modulus, breaking strength, breaking elongation, transversal Poisson ratio) for samples made from a resin whose Dammar is its main part. Based on this resin, were made composite materials, using as reinforcement fabrics from cotton, silk, flax and hemp. For each composite type were experimentally determined the same mechanical properties as in the case of resin based samples. Keywords: textile composites, mechanical properties, stress/strain curves, elastic properties, fractography
