Abstract

In order to investigate the most extreme conditions in which materials potentially applicable in reusable thermal shields can be operated, ultra-high-temperature ZrB2 ceramics with 20 vol.% MoSi2 were prepared using two different techniques, cold isostatic pressing (CIP) and robocasting (RC, an additive manufacturing technique), followed by consolidation using pressureless spark plasma sintering (SPS). The oxidation behavior of the resulting materials was analyzed in low-pressure dissociated air at three different temperatures, namely 1800, 2000 and 2200 K. Using XRD and surface and cross-section SEM (coupled with EDS), zirconia was found to form at all three temperatures, while silica was only present at 1800 K, with gaseous SiO forming at a higher temperature. The elaboration technique influences the density of the ceramic, and less dense materials undergo deeper oxidation. This investigation suggests that 2000 K is already beyond the maximum temperature threshold at which damage to ceramics is limited by the formation of protective silica. This study confirms that the selected material is a promising candidate for thermal protection applications. [ABSTRACT FROM AUTHOR]

Abstract

The use of metal fuels for future long-distance transportation has engaged the attention of researchers as cleaner substitutes to fossil fuels. The sustainability of their use can be attained through the reduction of their combustion oxide products using renewable energy sources. Thus, an innovative, sustainable, environmental-friendly and economically-beneficial process consists in the combustion/reduction cycles of the metal fuels/metal oxides. In this context, we performed vacuum-assisted carbothermal reduction of magnesia and alumina using concentrated solar energy aiming to improve the efficiency of the cycle. Considering magnesia reduction, solar experiments proved that a 96% Mg yield of highly pure (96%) agglomerates, of micron-sized particles and crystals, is reached by optimizing the reaction conditions: creating a swirl circulation in the Sol@rmet reactor (with numerical validation); mechanical milling of the C/MgO powders; probing the effect of metal catalysts (Fe, Ni, Fe-Ni); use of charcoal reducing agent with high fixed carbon content (by controlling the pyrolysis conditions); use of bentonite binder that showed a catalytic-like role. Considering alumina reduction, the main drawback was the formation of undesirable Al-oxycarbide by-products. Solar experiments proved that lowering the reactor pressure from 840 to 285 Pa allows to avoid the formation of Al2OC and to reach an Al yield of 77% of pure (91%) agglomerates of nano-and micro-sized particles. However, a further decrease of the pressure (< 200 Pa) is disadvantageous (43% Al yield) as the produced powders are easily re-oxidized (40% Al2O3). [ABSTRACT FROM AUTHOR]

Abstract

The use of metallic powders as substitute combustion fuels for transportation gain much interest due to their high energetic value, the absence of greenhouse gas emissions, and the ability to regenerate them. Herein, we studied their production through the reduction of magnesia in the Sol@rmet reactor, at low pressure, using concentrated solar energy and different charcoal reducing agents as sustainable sources. Previous kinetic studies suggested that the MgO/C phase boundary reaction is the dominant phase at the initial stage of reduction. Additionally, one of the main problems encountered at high temperatures is the sintering of MgO particles, which reduces their contact with carbon and in consequence the reduction rate. Thus, we investigated the effect of the charcoal properties (C-content, porosity, surface area…), milling, and binders on the metallic conversion yield and purity, proving that values up to 85% and 95% can be achieved during a progressive increase of the temperature.

Abstract

The spacecraft oriented code ARES developed at ON-ERA since 2005 to compute Earth and Mars atmospheric reentries is introduced. Then, a new 3D mesh displacement strategy to computed 3D space debris ablation is presented. This strategy is implemented in the material response solver MoDeTheC, which is one of the 4 independant solvers coupled within ARES code. Verification test cases show the capacity of the strategy to deal with important recession and shape changes. This strategy is then used in ARES software to rebuild a wind tunnel ablation test. Finally, the atmospheric reentry of a tank made of an orthotropic composite material is computed, taking into account degradation reaction and shape changes. Two coupling strategy in ARES software are used and compared.
