A novel device is adopted in order to experimentally investigate the effect of various loading rates on the pull-out response of a fastened composite joint configuration. The joint coupons comprise a composite plate made of the carbon/epoxy AS4/8552 material system and a centrally located titanium lockbolt. Tensile-type (pull) loading was applied to the specimens in a velocity range from quasi-static to 2.1 m/s. Both quasi-static and dynamic tests were conducted using the same specimen geometry and boundary conditions, which conform to international and industrial standards. The experimental work expands the limited literature and understanding of the mechanical response of composite pull-out joints under the action of dynamic loading. The main experimental observations revealed an increase of 15% regarding maximum load values when loading rate shifts from the static to the impact regime, while the failure patterns derived from static and dynamic tests were similar, although the latter presented a more intense damage zone.

为了实验地研究各种加载速率对固定复合接头结构的拉出响应的影响，采用了一种新颖的装置。联合试样包括一个由碳/环氧树脂AS4 / 8552材料系统制成的复合板和一个位于中心的钛锁紧螺栓。拉伸型（拉）载荷以准静态到2.1 m / s的速度范围施加到样品上。准静态和动态测试均使用相同的试样几何形状和边界条件进行，并符合国际和工业标准。实验工作扩展了有限的文献，并了解了在动态载荷作用下复合拉拔式接头的机械响应。
