“…Most of the work discussing the response of composites to shock loading has examined the material with the fibre plane normal to the loading axis. Overall, when shocked in this orientation, fibre based composites appear to behave in a manner similar to monolithic polymers, indeed Zaretsky et al [15] have made this point. However, it would be expected that when the fibre direction is orientated along the impact axis, the response would be quite different.…”

This high strain rate stress can be used to verify the bond strength between two layers. This method has been applied to Carbon Fibre Reinforced Polymer (CFRP) composite laminates, involved in aeronautic or defense industry. Experiments have been carried out on high power laser facility in the nanosecond regime. A velocimetry interferometer has been used to record the material velocity at the back surface of the samples. This study provides a comprehensive approach of the response of CFRP laminates of different thicknesses to a shock load normal to the fibres direction. The stress waves generation and propagation within the laminate and the induced delamination are key issues of this work. The main result is the ability of the technique to evaluate the out-of-plane strength of these laminates.

“…Despite their widespread application, there are few reports detailing their impact (shock) and dynamic strength properties, typically limited to low shock pressures [4][5][6][7][8][9]. There have also been investigations of the dynamic response of related (such as glass-or alumina-filled) polymer composites [10][11][12][13].…”

Abstract. The dynamic (shock) responses of two carbon fiber-filled polymer composites have been quantified using gas gun-driven plate impact experimentation. The first composite is a filament-wound, highly unidirectional carbon fiber-filled epoxy with a high degree of porosity. The second composite is a chopped carbon fiber-and graphite-filled phenolic resin with littleto-no porosity. Hugoniot data are presented for the carbon fiber-epoxy (CE) composite to 18.6 GPa in the through-thickness direction, in which the shock propagates normal to the fibers. The data are best represented by a linear Rankine-Hugoniot fit: U s = 2.87 + 1.17 × u p (ρ 0 = 1.536 g/cm 3 ). The shock wave structures were found to be highly heterogeneous, both due to the anisotropic nature of the fiber-epoxy microstructure, and the high degree of void volume. Plate impact experiments were also performed on a carbon fiber-filled phenolic (CP) composite to much higher shock input pressures, exceeding the reactants-toproducts transition common to polymers. The CP was found to be stiffer than the filament-wound CE in the unreacted Hugoniot regime, and transformed to products near the shock-driven reaction threshold on the principal Hugoniot previously shown for the phenolic binder itself.[19] On-going research is focused on interrogating the direction-dependent dyanamic response and dynamic failure strength (spall) for the CE composite in the TT and 0• (fiber) directions.
