  • Tensile characteristics of the composite are dependent on the specimen orientation.
  • The total strain energy during tension is related to the reinforcement quantity.
  • Degradation mechanism is associated strongly with a number of the reinforcing layers.
  • Mechanical properties of the composite are depend on the fabrication conditions.
The paper concerns the study of polymer-glass composite under tensile loading in order to determine changes in the tensile characteristics. Mechanical properties and features of damage zones important for operation and assessment of the technical conditions of the components made of this material are considered. Selected details of the experimental technique used are presented. The tensile characteristics of the polymer-glass composite are given. They were determined using specimens taken from various directions, with the main focus on the Young's modulus, elastic limit, yield point and ultimate tensile strength. An influence of the number of reinforcement layers, percentage content of the glass fibres as well as the resin quantity, on the mechanical parameters, are discussed.
