Reactions of Al-PTFE under Impact and Quasi-Static Compression

Figure 4

Energy absorption for Al-PTFE under quasi-static and dynamic compression. For static compression, each unreacted point represents the result of a single sample; each reacted point means the lowest energy level needed to initiate. For dynamic compression, an unreacted point means no reaction has been observed at that energy level; a partly reacted point means reaction was observed for at least one sample; a reacted point means all samples were reacted at that energy level. Notice that at energy of 100 J both reactions under static compression and under dynamic compression took place, which made the point look like an eight-pointed star.
