Abstract

To characterize the mechanical properties of PTFE / Al (73. 5 wt. % / 26. 5 wt. %) fluoropolymer-matrix reactive materials,quasi-static and dynamic compression tests at elevated strain rates and temperatures, as well as dynamic compression-shear tests based on hat-shaped specimens with predesigned shear bands of different widthsare conducted. Quasi-static (10 - 3 s - 1 ) and dynamic compression tests at elevated strain rates (3 ͓ 103 - 7 ͓ 103 s - 1 ) and temperatures (20 °C,100 °C, 150 °C,200 °C) show that the PTFE / Al material is a typical elasto-plastic material with strain hardening, strain rate strengthening and thermal softening effects. Dynamic compression-shear tests based on hat-shaped specimens with predesigned shear bands of different widths(500 μm,300 μm,100 μm) show that the difference in shear band widths induceslocalized thermal and temperature rise and hasa prominent effect on the dynamic response of fluoropolymer-matrix reactive materials.
