Özet:

 

This study highlights the influence of seawater absorption on Charpy impact properties of glass/epoxy composites. For this study, two groups of glass/epoxy composites that were produced by using vacuum infusion method were immersed in seawater at 25°C and 70°C temperatures and one group was immersed any condition. Specimens were keep in water until getting saturation point. The immersed specimens reached saturation at the end of sixth weeks (1000 h). Charpy impact test (having 15 J impact capacity) were conducted three groups that are dry samples, saturated samples and re-dried samples after saturation. From the Charpy impact test result it was observed that impact properties degradation occured due to hydrothermal aging. Compared to their non-immersed state, maximum impact stress energy of immersed specimen have dropped seriously, regardless of temperature. Also, as temperature increased, the reduction rate of maximum impact stress energy increased. Similar results occured at re-dried group. That is the decrease rate in aged samples at 25°C is 27.3%, whereas this rate is 30.03% in aged samples at 70°C. However, when compared to their dry state, the decrease in maximum impact stress in the re-dried group is considereably lower than in the satureted group. The decrease rate in re-dried samples aged samples at 25°C is 2.6%, whereas this rate is 7.77% in re-dried samples aged at 70°C.
