摘要: The effects of calcined diatom (CD) and natural (ND) frustules filling (0–12 vol.%) on the quasistatic tensile quasi-static high strain rate compression behavior an epoxy matrix were investigated experimentally. testing frustules-filled neat samples was performed in a Split Hopkinson Pressure Bar set-up. increased stress values at constant decreased failure strains matrix. Compression tests results showed that both elastic modulus yield strength rates. While, higher strengthening effect sensitivity found with ND filling. Microscopic observations revealed two main deformation modes rates: debonding from and/or crushing frustules. However, filled composites rates dominated by fracture
