Abstract

Abstract: The transverse three-point bending tests were used to study the impact of Z-pin diameter and volume content on the connection performance of composite toughened simplified components. Compared to the blank control group, the payload of Z-pin toughened specimens increased by 48.41% to 96.97% and the total energy dissipation by 661.88% to 748.72% with an increase in Z-pin volume content. The results of this test show that toughened specimens’ load carrying capacity can be significantly increased by using high Z-pin volume content. The load carrying capacity of the test group with the Z-pin diameter of 0.5 mm is slightly greater than that of the test group with the Z-pin diameter of 0.3 mm, but the test group with the Z-pin diameter of 0.3 mm has better stability in the case of the same Z-pin volume content of 0.4%. According to the test results, Z-pin implantation can improve the payload and energy dissipation of the composite toughened class’s simplified members and, obviously, enhance the connection performance of the toughened specimens.
