Abstract
Phenolic resins are used in many aspects of everyday life, e.g. as the matrix material for carbon fibre laminates used in the aerospace industry. Consequently, detailed knowledge of this material, especially while under shock loading, is extremely useful for the design of components that could be subjected to impact during their lifespan. The shock Hugoniot equations of state for phenolic resin (Durite SC-1008), with initial density of 1.18 g cm−3 have been determined using the plate-impact technique with in situ manganin stress gauges. The Hugoniot equation in the shock velocity–particle velocity plane was found to be non-linear in nature with the following equation: US = 2.14 + 3.79up − 1.68u 2p . Further, the Hugoniot in the pressure–volume plane was observed to largely follow the hydrostatic curve. Lateral gauge measurements were also obtained. An ANSYS AutodynTM 2D model was used to investigate the lateral stress behaviour of the SC-1008. A comparison of the Hugoniot elastic limit calculated from the shear strength and measured sound speeds gave reasonable agreement with a value of 0.66 ± 0.35 GPa obtained.
