High‐strain‐rate mechanical performance of particle‐ and fiber‐reinforced polymer composites measured with split Hopkinson bar: A review

Abstract

Reinforcing polymers with particles and fibers has been a common strategy for decades, in order to make them suitable for high-demanding industrial applications. As composites often undergo dynamic loads, it is important to understand their behavior under such conditions. This review first classifies the types of polymer composites and then explains their failure behavior under tension and compression loading, followed by an overview of some of the experimental procedures used to characterize the polymer composites' dynamic mechanical performance. Afterward, the most significant findings in terms of the highstrain-rate compressive and tensile strength and modulus of polymer composites are thoroughly discussed. The results, available in the literature, on the mechanical properties of polymer composites under quasi-static conditions are also presented and compared with the high-strain-rate data. The differences are explained by discussing the changes in the structural configurations of polymer matrices under quasi-static and dynamic loads. Lastly, conclusions and future perspectives are given, with the intent of highlighting the most promising polymer composites that can be used for a wide variety of applications.

Dynamic response of Advanced Placed Ply composites

“…The strain rate dependency of composites is typically characterized using Split Hopkinson Bar (SHB) experiments, which provide the stress-strain curves of a material at different strain rates [9]. The high strain rate behavior of conventional carbon fiber epoxy composites has been extensively studied.…”

Numerical Conversion Method for the Dynamic Storage Modulus and Relaxation Modulus of Hydroxy-Terminated Polybutadiene (HTPB) Propellants

“…Further, current studies mainly focus on the strength and stiffness of materials, the analytical prediction methods, and the development of constitutive models [ 29 , 30 , 31 ]. However, materials in industrial applications are subjected to not only static but also dynamic loads, probably both at the same time, or both occurring sequentially [ 32 ]. Therefore, it is of great importance to study the combination of the dynamic and static studies of propellants to achieve the inter-conversion of the relaxation modulus and dynamic modulus [ 33 , 34 ], so that dynamic and static experiments or simulations can mutually corroborate.…”

Effect of weave pattern on high strain rate performance of glass/polytetrafluoroethylene composites

“…The split Hopkinson pressure bar (SHPB), first introduced by Kolsky, [3] is the most widely used technique for the direct determination of HSR mechanical properties. [4] Fiber reinforcements generally used for HSR applications are glass, carbon, aramid, ultrahigh molecular weight polyethylene (UHMWPE) and basalt. Research performed on various materials ranging from polymers, metals and composites have proven the rate dependency of these materials.…”
