Özet

In this study we have investigated thermomechanical and solid particle erosion behaviour of ABS/PA6 composites reinforced with CaCO3 particles and SGF. ABS/PA6 composites were reinforced with CaCO3 particles and SGF at different weight ratios (0, 10, 30, 15/15 wt.%). Composite materials were manufactured by twin screw extruder and injection molding machine. Thermomechanical properties were investigated by dynamic mechanical analysis (DMA) method. Moreover erosion wear behaviour was investigated on solid particle erosion test machine. Experimental results show that thermomechanical properties significantly depend on particle types and weight ratios. While storage modulus was found to be maximum for 30 wt.% SGF-reinforced samples, the loss modulus was found to be maximum for 15/15 wt.% hybrid samples. Moreover minimum loss factor values were found for hybrid samples, but glass transition temperature of samples were not effected significantly with CaCO3 and SGF reinforcement. Erosion behaviour depends on particle impact angle, the type of reinforcing particles and their weight ratios. Maximum erosion rates were found at impingement angle of 30 for 30 wt.% CaCO3-filled samples. According to experimental results both CaCO3 and SGF reinforcement have positive influence on thermomechanical properties. However CaCO3 and SGF reinforcement have reduced the solid particle erosion resistance of ABS/PA6 composites.
