De-lamination Strength Testing

De-lamination is the separation of the layers in a laminate. Laminate is a sheet of material that has been created by stacking thin layers, or plies, and bonding them together. De-lamination can occur locally, in a small area of the laminate, or it can affect the entire laminate. In laminated materials, repeated cyclic stresses, impact, and so on can cause layers to separate, forming a mica-like structure of separate layers, with significant loss of mechanical toughness. A wide range of structural applications are possible; however, amongst other considerations the performance of these materials under crash and impact loading is a...
