Evaluation of Filler Effects on the Dynamic Mechanical Behavior of HTPB-Elastomer Used as Binder in Exemplary Composite Formulations
Autor: Mauricio Ferrapontoff Lemos, Günter Mussbach, Manfred August Bohn
Publikováno v: Journal of Aerospace Technology and Management, Vol 9, Iss 3 (2017)
This study aims to evaluate the dynamic mechanical properties of a binder, used in composite propellants, with increasing amount of different solid fillers. Dynamic Mechanical Analysis (DMA) is performed to determine the region of glassrubber transit

Simulation of Heat Flow Curves of NC‐Based Propellants – Part 2: Application to DPA Stabilized Propellants
Autor: Manfred A. Bohn, Daniel G. Itkis
Publikováno v: Propellants, Explosives, Pyrotechnics. 46:1204-1215
Measuring of heat flow curves at temperatures near the in-service range have become a standard for stability and compatibility assessments of nitrocellulose (NC)-based energetic materials. The typical technique to realise this demand is heat flow mic

The Connection Between the Parameters of WLF Equation and of Arrhenius Equation
Autor: Manfred A. Bohn
Publikováno v: Propellants, Explosives, Pyrotechnics. 44:696-705
The description of the change in characteristic temperatures of thermomechanical and viscoelastic proper-ties of polymers and elastomers with deformation frequency or of temperature dependence of polymer proper-ties is widely achieved by two equation

Application of azide-containing molecules as modifiers of HTPB
Autor: Thomas Keicher, Maurício Ferrapontoff Lemos, Manfred A. Bohn, Luis C. Mendes
Publikováno v: Journal of Thermal Analysis and Calorimetry. 137:411-419
Hydroxyl-terminated polybutadiene (HTPB) has been widely modified and copolymerized with azide substances to be applicable as an elastomer binder in a composite solid propellant (CSP). This research presents a systematic evaluation of the HTPB chemic

Solid-Liquid Adhesion Energies of Composite Propellant Components Determined by Solution Calorimetry
Autor: Michael M. Nardai, Manfred A. Bohn
Publikováno v: Propellants, Explosives, Pyrotechnics. 42:728-735
The energetic or adhesive interaction between binder matrix and solid fillers as well as plasticizers and fillers is a property determining mechanical properties as strain capacity and stress at maximum or stress at break. To know such interaction en

Characterization of Aging Behavior of Butacene® Based Composite Propellants by Loss Factor Curves
Autor: Manfred A. Bohn, Tijen Seyidoglu
Publikováno v: Propellants, Explosives, Pyrotechnics. 42:712-723
Butacene® is a polymeric binder with ferrocenyl groups chemically bonded to HTPB backbone. Through incorporation in the AP−Al composite propellant formulation, it leads to high burning rates (BR) >20 mm/s at 7 MPa, and low pressure exponents n
