The design process requires an understanding of the static and high strain rate mechanical behaviour of the materials used. In this study, the tensile stress–strain curves of Araldite®2015 epoxy-based adhesive were investigated at strain rates of (1200 - 1900 s-1), by adding aluminium powders of different particle sizes (44, 100, and 250μm) at weight-fractions of 2, 6 and 10%, respectively. In order to conduct impact tension tests using a conventional Split-Hopkinson Pressure Bar (SHPB) device a new apparatus was proposed and tested so that compressive axial impact loads can be converted to tensile loads through a conventional SHPB device. The tensile tests at various strain rates revealed that both of neat and microparticle reinforced adhesive specimens exhibited high sensitivity to strain rate levels. A trend of increasing ultimate strength at higher strain rates occurred, with an enhancement of up to 41%. The microparticle reinforced adhesives exhibited lower sensitivity for low particle weight-fractions, but the particle size influenced partly strain rate sensitivity for all particle weight-fractions. The mechanical behaviour of microparticle reinforced adhesives at various strain rates was critical in an axial tensile impact load.
