Laser ignition has been widely studied, and is regarded as a potential initiation technique in pyrotechnics owing to its simple sequence, good safety, high consistency, strong anti-electromagnetic interference ability. One of the most important requirements for practical application laser reduction energy, which requires both light absorption photothermal properties energetic materials or additives materials. Therefore, this review, recent progress different their laser-induced performances...
In this research work, both natural weathering and artificial processes were carried out to investigate the effects of multi-functional epoxy chain extender (Joncryl ADR 4370) content on degradation mechanical properties molecular weight poly(butylene adipate-co-terephthalate) (PBAT). The carboxyl end-groups PBAT decreased significantly with an increase in from 0 1.5 wt%. Similarly, initially increased then because formation a crosslinked network structure under influence excessive...
The ultrafast and large temperature rise of energetic graphene oxide during laser pulse irradiation.
Three kinds of Al flyer plates with different nanostructured absorption layers were in situ prepared by a direct laser writing technology to improve the energy conversion efficiency laser-driven assembly. Microstructures, light absorption, and velocity acceleration chamber investigated. The reflectance for flyers at 1064-nm wavelength can be reduced from 81.3 9.8% layer. terminal 50-μm-thick irradiated 60-mJ pulse is 831 m/s, while an situ-fabricated nano-absorption layer reaches up 1113 m/s...
Abstract Aluminum nanoparticles were added into pentaerythritol tetranitrate (PETN) to decrease the near‐infrared (NIR) laser initiation power. The effects of Al on minimum power all fire investigated under 1064 nm initiation. mechanism was studied using differential scanning calorimetry, reflectance spectroscopy, laser‐induced breakdown and shadowgraph technique. Results showed that addition could prominently PETN. PETN doped with 0.5 % be reliably initiated 40 mJ energy (1064 nm, 14 ns)....
In this paper, the influence of Al/Ni reactive multilayer films on laser ablation induced plasma process is investigated. Laser single Ni layer and RMFs was performed by nanosecond pulsed beam with 1064 nm wavelength. The characterization methods were applied for researching structure chemical composition transmission electron microscopy, X-ray photoelectron spectroscopy, atom probe tomography. effects properties then systematically investigated in terms temperature, density ionization....
Reactive multilayer films (RMFs) are a type of thermite nanoenergetic film, which can be potentially applied to an exploding foil flyer generator (EFFG). Herein, Al/Ni RMFs with bilayer thickness 500 nm integrated into layer by magnetron sputtering method. The effects interface on the properties EFFG systematically investigated in terms electrical behavior and velocity. is controlled annealing, whose structure chemical composition confirmed X‐ray diffraction transmission electron microscopy....
Al, MgAl, and MgAl hydride films with an overall thickness of 1 μm are prepared by magnetron sputtering. Their surface morphology, structure, heat properties investigated using scanning electron microscopy (SEM), X‐ray diffraction (XRD), laser flash method. XRD results confirm that hydrogen is successfully stored in the as MgH 2 Mg(AlH 4 ) observed. Laser show thermal diffusivity film equivalent to much lower than Al film. Furthermore, these irradiated pulsed lasers under 20.4, 30.6, 49.8,...
