Quasi-static behaviour of composite joints with protruding-head bolts

摘要: An experimental study of the quasi-static behaviour composite bolted joints under tensile and compressive loading has been performed. The joint plates made quasi-isotropic 0°-dominated lay-ups were fastened by two, four, or six titanium bolts. Two specimen configurations tested: single lap double lap. Strain gauges applied in order to measure strain between bolt rows calculate load transfer rows. Bolt-movement measurements performed using extensometers examine static loading. obtained results showed that with four bolts perform better resistance than two distribution is significantly affected presence their load-transfer calculations different slightly amounts load.
