Damage tolerance improvement of composite T-joint under pull-up conditions using an interlocking-fiber-based crack arrester

One of the difficulties in composite structural application is joining components. A T-joint is a critical component in aircraft structures that transfers loads between vertical and horizontal panels. However, in T-joints, a critical concern is that cracks occur in the deltoid and immediately propagate along the flange-skin interface. Therefore, introducing crack arrest features at the flange-skin interface is effective in improving the damage...
