Functionally Graded Nanofiber Interlayers for Hydrothermally Aged Glass/Epoxy Laminates: Mechanical Performance and Electromagnetic Attenuation

open access: yesPolymer Composites, EarlyView.
Functionally graded Ag/Fe3O4‐loaded PAN nanofiber interlayers for improved mechanical performance and EMI attenuation in GFRP laminates. ABSTRACT Functionally graded Ag/Fe3O4‐loaded polyacrylonitrile (PAN) nanofiber interlayers were placed between selected glass fabric plies to improve interlaminar damage resistance in glass fiber‐reinforced polymer ...

Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.

Development of NMP‐001, A Nitromethane‐Based Green Propellant

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT This paper discusses the development of a model monopropellant that is aimed at exploring the applicability of nitromethane‐based propellants as an alternative to hydrazine. This approach addresses the challenges faced by HAN‐, ADN‐based propulsion by being more cost‐effective while providing similar performance figures.

Stop Using Limiting Stimuli as a Measure of Sensitivities of Energetic Materials

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Accurately estimating the sensitivity of explosive materials is a potentially life‐saving task that requires standardised protocols across nations. One of the most widely applied procedures worldwide is the so‐called ‘1‐In‐6’ test from the United Nations (UN) Manual of Tests in Criteria, which estimates a ‘limiting stimulus’ for a material. In

Exploding Bridgewire (EBW) Detonators: An Example of Synergistic Multiphysics

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Exploding bridgewire (EBW) detonators are highly temporally reproducible explosive devices that require the rapid discharge of a high‐voltage capacitance to operate and so are immune to most of the accidental hazards associated with traditional electric detonators.

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.
