“…Fibre failure usually occurs after delamination [23] and so ignoring it in the model still gives good predictions of initial impact damage. However, because delamination reduces the bending stiffness and allows greater deformation to occur, it also has a beneficial effect in limiting the stresses that lead to fibre failure.…”

The mechanisms by which delamination contributes to the failure of fibre-reinforced composites are reviewed. Through-thickness failure owing to interlaminar stresses is considered first, and the effect of delamination in impact and compression after impact. The way in which in-plane failure can occur by delamination and matrix cracks joining up to produce a fracture surface without the need to break fibres is considered next. Examples of quasi-isotropic laminates loaded at different off-axis angles, and with different numbers and thicknesses of ply blocks show large differences in unnotched tensile strength controlled by delamination from the free edge. Similar mechanisms determine the strength of notched specimens and give rise to the hole size effect, whereby tensile strength increases with decreasing hole diameter owing to increased delamination and splitting. Open hole tension and over-height compact tension tests with constant inplane dimensions show a transition in failure mode with increasing ply block thickness from fibre-dominated fracture to complete delamination. In all these cases, the critical factor controlling strength is the relative propensity to delaminate.

“…The properties and damage behavior of the composite material laminates interface phase are studied by many scholars [1][2][3][4][5]. Some scholars studied the interface stress transfer characteristics of resin matrix composite between the fiber reinforced phase and matrix under thermal-load conditions using experiment and simulation analysis method, and found that the surface shear stress is in a parabola distribution.…”

Abstract. The Hashin failure model and the 3D progressive damage method-based user material subroutine are employed to characterize the impact damage characteristics of composite layer, and surface based cohesive behaviour are introduced to characterize the interlaminar mechanical property in this paper. The dynamic response process of the carbon/epoxy composite laminates subjected to low-velocity impact load under different interlayer surface strength conditions are simulated, and the effects of interlayer interface strength on the ballistic property of composite materials are emphatically analysed. Results show that the impact dynamic response of composite laminated plates is a process of stress waves propagation, reflection, and interference between layer and layer. The kinetic energy dissipation of bullet varies depending on the interlayer surface strength of carbon/epoxy composite laminates. The kinetic energy absorbing performance of carbon/epoxy composite laminates is directly altered by the interlayer surface strength. The interlayer surface strength of laminates also directly impacts of the elastic strain energy carbon/epoxy composite and the kinetic energy dissipation of bullet in laminates failure. Namely, the transformed form of the bullet kinetic energy is affected by the interlayer surface strength significantly. In general, the interlayer surface strength presents a significant role on whether the failure form, the contact force, the kinetic energy dissipation process, the elastic strain energy composite laminates or the kinetic energy dissipation of bullet in laminates failure during the impact process.
