Özet

In this study, the effects of improvement methods on the mechanical and thermal properties of textile fiber reinforced (T-FRP) composites were investigated. Five different chemical methods namely, silane treatment, alkaline treatment, alkali-silane treatment, maleic anhydride, and alkali-maleic anhydride coupling agents were applied to evaluate the suitable process parameters (concentration, soaking time, ratio by weight) for the enhanced properties of T-FRP composites. Tensile, three-point flexural and impact tests were performed on both untreated and treated composites for comparison purpose. Treated and untreated T-FRP composites were characterized using scanning electron microscopy, differential scanning calorimetry, and Fourier-transform infrared spectroscopy to evaluate thermomechanical properties of composites. Results show that a significant improvement up to 60-70% can be seen on the mechanical properties of T-FRP composites via improving the interfacial adhesion and compatibility between fiber and matrix.
