Abstract

Within this paper, extended experimental researches regarding the behavior of plain weave carbon fabric-reinforced epoxy composite laminates subjected to three-point bend tests have been carried out. As reinforcement material, 200 g/m2 specific weight plain weave carbon fabric has been used. Various specimens have been cut from plates of five, six and seven layers of epoxy resin impregnated fabric according to ISO 14125:1998: “Fibre-reinforced plastic composites – Determination of flexural properties”. These plates have been cured in an autoclave with controlled temperature and pressure. Following mechanical properties have been determined during three-point bend tests: Young’s modulus of bending, stiffness, flexural rigidity, maximum bend stress/strain at maximum and minimum load/extension, load/stress/strain at maximum and minimum load/extension and so on..
