Failure Properties

This paper aims to study dynamic progressive failure properties of glass fiber composite/aluminium hybrid laminates under low-velocity impact. Intralaminar damage models using Puck failure criteria and strain-based damage evolution laws for composite layers are implemented by developing finite element codes using ABAQUS-VUMAT (user dynamic material subroutine), the interface delamination is simulated by bilinear cohesive model in ABAQUS and the mechanical properties of aluminium layers are described using the Johnson-Cook model. Effects of different layer thickness and impact energy on the impact force–time/displacement curves of glass fiber composite/aluminium laminates under low-velocity impact are discussed. Besides, damage evolution behaviors of matrix and delamination interface are explored. Finally, energy dissipation mechanisms due to intralaminar dynamic progressive failure, interlaminar delamination of composite layers and plastic deformation of aluminium layers are studied. Relatively good agreement is obtained between experimental and numerical results.

Simplified Finite Element Model

This paper aims to explore the low velocity impact response of glass fiber composite/aluminum hybrid laminates (GLAREs). Puck’s criterion with an efficient algorithm and damage evolution laws based on equivalent strain are used for intralaminar damage models, and the interface delamination is simulated by the bilinear cohesive model in ABAQUS, besides, the Johnson-Cook model is applied to describe the mechanical properties of aluminum layers. Numerical analysis is performed on GLAREs with different impact energy based on simplified finite element model in order to study the damage evolution behaviors of composite layers and interface. In addition, the energy dissipation mechanisms due to damage of composite layers including fiber tension, fiber compression, matrix tension and matrix compression, interface delamination and plastic deformation of aluminum layers are also explored. Meanwhile, the simulation results with simplified model have a good agreement with the experimental results.

The Impact

In the current study, the low-velocity impact response of hybrid-laminated composites based on the twill woven fabrics was investigated experimentally. The following five different types of carbon–aramid/epoxy hybrid laminates were produced and tested, (a) two types of interply hybrid, (b) two types of sandwich-like interply hybrid, and (c) intraply hybrid. Non-hybrid carbon and aramid twill woven laminates were also tested for comparison. The effects of the hybrid structure on the impact properties such as the peak load, the ductility index, and damage area were discussed. The impact damage resistances of specimens were evaluated by comparing damage images taken from both the impacted and the non-impacted surface. The damage and failure mechanisms were analyzed from the impact damage morphologies using ultrasonic C-scan and three-coordinate measuring device. Under the same impact energies, the interply hybrid laminates with carbon fabric on the impact surface have higher impact damage resistance. It can be concluded that placing of high stiffness carbon fabric at highly stressed regions as reinforcement would result in enhanced properties, and the damage tolerance performance of composites with interply hybrid structure are better than those of other hybrid composites.
