A review of composite structures subjected to dynamic loading

“…Different conclusions on strain rate effects can be attributed as that the trend of composite materials hardening can be influenced by numerous parameters including, but not limited to, the material system of fibre and matrix [21], the manufacturing process which influences the interfacial properties between fibre and matrix and lay-ups, the reinforcement architecture, the range of strain rate under consideration [6], the loading direction and the time-dependent characteristic of damage propagation. Thus, experiments at different strain rates should be carried out when any of aforementioned factors are changed to fully understand the mechanical performance of woven composite.…”

Woven composite has been increasingly employed in engineering applications undergoing complex loading conditions. For effective use of composite materials, it is essential to fully understand the mechanical behaviour of composite at different strain rates. In the present study, both in-plane tensile and compressive mechanical properties of a carbon/glass hybrid plain weave composite were experimentally investigated over the strain rate range from 0.001 to 1000 s ¡1 . High strain rate tests were carried out using Split Hopkinson Pressure and Split Tensile Bar apparatuses, respectively. Experiments were performed at the axial direction of 0 and 90 , and the off-axial direction of 45 considering the tension/compression asymmetry and anisotropy characteristic. The results indicated that the in-plane mechanical performance was strain rate sensitive under both tensile and compressive loadings. Highly direction-dependent and tension/compression asymmetric characteristic was observed under quasi-static and high strain rate loadings. The elastic modulus showed no strain rate sensitivity for the 0 axial tension. However, for other loading conditions, the elastic modulus was enhanced by 1.7À7.2 times under high strain rate loading. The strength was increased by 1.2À2.5 times at 1000 s ¡1 compared with that under quasi-static loading for different loading directions. For higher strain rate sensitivity under compression than tension, the asymmetry was less obvious with the increase of strain rate. Two phenomenological models were proposed to quantitatively fit the relationship between the strength property and strain rate, which showed great consistency between the experimental and fitted results.

“…Several researchers have utilized various materials in the different layers of multilayer composite structures to balance the stiffness, flexibility and ductility of the composite structures. The composite structures are also becoming acceptable because of the high strength at comparatively low weight of the structure [1] individual layers of multi-layer composites. In addition, the rehabilitation of core portion of the composite structure is difficult and also costly and hence less or almost no damage is expected in this layer.…”

This paper reviews the recent research progress on multi-layer composite structures composed of variety of materials. The utilization of multi-layer composite system is found to be common in metal structures and pavement systems. The layer of composite structure designed to encounter heavy dynamic energy should have sufficient ductility to counteract the intensity of energy. Therefore, the selection of materials and enhancement of interface bonding become crucial and both are discussed in this paper. The failure modes have also been explored in conjunction with stresses at failures and inferred solutions are also revealed. The paper attempts to reveal all technical facts on multi-layer composite structure in a broad field. 
