The Stability

The experimental progress of laser equation of state (EOS) studies at Shanghai Institute of Laser Plasma (SILP) is discussed in this paper. With a unique focal system, the uniformity of the laser illumination on the target surface is improved and a laser-driven shock wave with good spatial planarity is obtained. With an inclined aluminum target plane, the stability of shock waves are studied, and the corresponding thickness range of the target of laser-driven shock waves propagating steadily are given. The shock adiabats of Cu, Fe, SiO2 are experimentally measured. The pressure in the material is heightened remarkably with the flyer increasing pressure, and the effect of the increasing pressure is observed. Also, the high-pressure shock wave is produced and recorded in the experimentation of indirect laser-driven shock waves with the hohlraum target.

Aluminum Target

Studying the armor-piercing effect of armor-piercing bomb that attacks aluminum target is essential, because the target can be considered the simulation of the actual fight equipment. Based on the hypothesis about building the fraction field, the armor-piercing effect of armor-piercing bomb is analyzed, and the velocity and the intruding depth parameter model of armor-piercing effect are established. Taking a certain armor-piercing bomb as example, the intruding processes of armor-piercing effect are simulated by using the nonlinear finite element analysis program LS-DYNA, while aluminum target simulates the wall of combat equipment in two different conditions. At last, the finite element simulated results are given and analyzed that agree with the experiments.

Projectile Impact

The influence of target span as well as configuration was studied with 1 mm thick 1100H12 aluminum target subjected to19 mm diameter ogive nosed projectile impact. The effective span of 1 mm thick monolithic target was varied as 95, 190, 285, 380 and 475 mm. The configuration of 255 mm span diameter target was varied as 1 mm thick monolithic, double layered in-contact (2 x 0.5 mm) and double layered spaced. The spacing between the layers was also varied as 2, 5, 10 and 20 mm. The target was impacted normally by ogive nosed projectile to obtain the ballistic limit, failure mode and deformation. The ballistic limit was found to increase with an increase in span diameter. The monolithic target offered highest ballistic limit followed by layered in-contact and spaced targets respectively. The variation of spacing between the layers did not have significant influence on the ballistic limit.

Barrier properties are achieved in PET food packaging by using additives, coatings or multi-layers. An analytical model to predict the contamination during multiple recycling steps of this packaging is proposed. This model shows that lower contents of non-PET materials should be achieved to promote a valid recycling chain. A possible solution is using nano-technologies because of the very small amount of added material. Results are shown in the case of PVD coatings with aluminum target, and PET nano-composites. In both cases, less than 0.1 wt% of aluminum is able to reduce the oxygen transmission ratio of the PET packaging down to 50% of the virgin PET sheet.
