Özet

In this experimental study, under conditions of static loading, load-bearing performance of pin connected multilayered (angle-ply) glass fiber-reinforced polyphenylenesulphide matrix composites with [(0 degrees/90 degrees)](4s) and [(0 degrees/90 degrees)/(+/-45 degrees)](2s) stacking sequence was analyzed. The experiments were carried out according to the ASTM D953. The ratio of the distance between pin center and sample end, to pin diameter E/D; and the ratio of sample width to pin diameter W/D, were changed systematically during the experiments. From the results of the experiment, maximum bearing failure loads were obtained for [(0 degrees/90 degrees)/(+/-45 degrees)](2s) lay- up with geometric parameters of D = 10 mm and W/D = 2. Macro images belonging to failure modes, which occurred as results of the tests were examined. In addition to this, from the fractographic examinations carried out with scanning electron microscope, it was concluded that the geometric parameters intimately affect fracture morphology.
