abstract This work describes polyester matrix composite materials with diversified reinforcement materials, namely glass, carbon, and a natural material (jute). These reinforcement fibres were utilised in the form of fabrics with a canvas-like weave and basis weight ranging from 300÷400 g/m2. The mass fraction was uniform in each of the materials that were produced, namely 40% of the baseline in comparison to the materials that were subjected to testing. The composites were produced by the vacuum pressure infiltration method, RTM (resin transfer moulding), thereby creating laminates. To assess the mechanical properties of the composites, static tensile strength tests were carried out according to PN-EN ISO 527-1:2016; the bending strength was determined according to PN-EN ISO 178:2011, and the impact strength was tested by the Charpy method according to PN-EN ISO 179-1:2010. The density of these composites was determined by the hydrostatic method according to standard PN-EN ISO 1183-1:2013-06.
