摘要: Z-pinning is a newly developed technique to enhance the strength of composite laminates in thickness direction. Recent experimental and theoretical researches manifest that z-pins can significantly improve mode I fracture toughness double cantilever-beam tests II end-notched-flexure beam tests. From practical point view, buckling accompanying delamination typical failure laminated structures. For purpose complete understanding on z-pinning towards an improvement mechanical behaviour composites, present study, numerical approach applied investigate z-pinned with initial delaminations under compression. The results indicate effectively increase compressive provided imperfection within certain range. magnitude consistent available data.
