In order to simulate composite response to hypervelocity impact, reliable numerical models are primordial to obtain predictive simulations. In particular, an accurate equation of state (EOS) is required to predict hydrodynamic behavior of the material under high stresses and strains. For the design of such EOS, several experiments covering planar plate impacts and stress wave generation by electron beam were performed on a woven composite of Basalt-fibers/RTM6-Epoxy used in aerospatial protective applications. Two planar plate impacts using SYLEX light gas-gun, with impactor speed of 1105 and 1169 m/s, generated plane stress wave up to 15 GPa in the sample. On the other hand, pulsed electron beam with the CESAR facility was used to generate quasi-plane stress wave of 1 GPa in the composite. In both experiments, laser interferometer velocimeter measured the free surface velocity of the samples. Using impedance adaptation and shock accumulation method, data about Hugoniot equation and release isentrope up to 15 GPa were obtained and compared to litterature data. Under several assumptions, two equations of state were designed and simulations using the Finite Element Code HESIONE were performed. After comparison with experimental results, it appears that including compaction phenomena in the equation of state brings better correlation with the experimental data.
