Özet

In this study, an experimental investigation was carried out, in order to Study pin-bearing strength, failure modes under various clamping moments depending on the geometrical parameters. Two different geometrical parameters were investigated. For that reason, the ratio of the distance from the pin centre to the top edge top in diameter (E/D), and the ratio of the specimen width to the pin diameter (W/D) were suitably varied, in order to verify their influence on the failure modes consisting of net-tension, cleavage and bearing. Totally, 160 specimens were tested. The mechanical properties of prepreg composite were obtained from standard tests. Experimental results showed that failure modes and bearing strengths were strictly influenced from increasing value of applied clamping moments and geometrical parameters.
