Influence of water absorption on chosen strength properties of single-polymer polyester composites
Polimery 2018, No 4, 264
Investigations of the selected properties of single-polymer polyester composites (SPC) in dry condition and immersed in water are presented. Materials were tested for possible applications in shipbuilding. Water absorption till saturation limit was examined, at temperatures of 3, 23 and 100 °C, through the determination of water diffusion coefficient. Some material properties were determined through impact resistance tests of materials varyingin fiber content [0 (A), 5 (B), 10 (C), 15 (D), 20 wt % (E)]. The highest impact resistance (6 J/cm2) was found for the composite with more than 15 % of reinforcement in dry condition.
