Z-pin bridging in composite laminates and some related problems

Liu, Hong-Yuan and Yan, Wenyi and Mai, Yiu-Wing (2006) Z-pin bridging in composite laminates and some related problems. Australian Journal of Mechanical Engineering, 3 (1). pp. 11-19.


This paper reviews our recent studies on z-pinning of composite lamiantes. The contents include theoretical, numerical and experimental studies on the Mode I and Mode II z-pinned delamination growth and the corresponding bridging laws. Test methods to evaluate the z-pin bridging law will be discussed. Comparisons of experimental results and theoretical predictions for the z-pinned double-cantilever-beam (DCB) subjected to mode I delamination with a pre-determined bridging law are provided to confirm the reliability of the methods. A parametric study by finite element method (FEM) is presented for both Mode I and Mode II z-pinned delaminations. In addition, the effect of loading rate on z-pinned DCB delamination and the bridging effect of z-pinning on the buckling of composite laminates are also given.
