“…One camera was used to capture the global response of the composite joints. The second camera focussed on the region around the filler between web and skin as previous work on composite T-joints [12][13][14]22,23] had shown that damage initiated in this location. A random speckle pattern was applied onto the front surface of the filler region allowing the use of digital image correlation (DIC) technique to obtain additional information about the strain fields in the location where damage was thought to initiate.…”

To understand the influence of the fibre architecture of 3D woven composite T-joints on mechanical performance, as well as the benefits that 3D woven T-joints can offer over the equivalent 2D laminates, experimental testing is performed on two types of 3D woven T-joint with only weave variation at the junction, and one type of 2D woven laminate T-joint. A quasistatic tensile pull-off loading is selected in this work as this out-of-plane load case is one of the typical loading conditions for such T-joint structures. The significant advantages of 3D woven composite T-joints in terms of ultimate strength and damage tolerance over the 2D alternative were identified in the testing. More importantly, this work showed that variation in the fibre architecture can considerably enhance properties such as delamination resistance and total energy absorption to failure, as well as increasing slightly the stiffness and initial failure load. This experimental assessment has demonstrated that using 3D woven reinforcements is an effective way to improve the load-bearing capability of composite T-joints over laminates, and also that this improvement could be optimised with regard to fibre architecture.

“…Koh et al [15] reported that the capacity of pins to improve the structural properties of z-pinned composite structures was greater for thicker than for thinner laminates. Park et al [14] showed that the ultimate load of z-pinned laminated T-joints increased when the pin diameter was reduced (while keeping the pin volume content constant). All of these data suggest a strong influence of reinforcement pin geometry upon the enhancement of delamination resistance.…”

“…The z-pinning method has also been examined for its ability to improve the mechanical performance of composite structural joints, e.g. T-joints [12][13][14][15], which are prone to through-thickness damage in the form of debonding. The bridging behavior of z-pins in bonded joints is similar to their behavior in laminates.…”
