“…The utilization of biocomposites can mitigate this issue. In this context, Azad et al [72] incorporated silica nanoparticles to retard flame formation and spread within a jute/thermoplastic starch (TPS) matrix. The addition of these nanoparticles can also positively influence mechanical properties by enhancing tensile, flexural, and impact resistance properties [73].…”

The issue of thermal control for space missions has been critical since the early space missions in the late 1950s. The demands in such environments are heightened, characterized by significant temperature variations and the need to manage substantial densities of heat. The current work offers a comprehensive survey of the innovative materials and thermal fluids employed in the aerospace technological area. In this scope, the materials should exhibit enhanced reliability for facing maintenance and raw materials scarcity. The improved thermophysical properties of the nanofluids increase the efficiency of the systems, allowing the mass/volume reduction in satellites, rovers, and spacecraft. Herein are summarized the main findings from a literature review of more than one hundred works on aerospace thermal management. In this sense, relevant issues in aerospace convection cooling were reported and discussed, using heat pipes and heat exchangers, and with heat transfer ability at high velocity, low pressure, and microgravity. Among the main findings, it could be highlighted the fact that these novel materials and fluids provide enhanced thermal conductivity, stability, and insulation, enhancing the heat transfer capability and preventing the malfunctioning, overheating, and degradation over time of the systems. The resulting indicators will contribute to strategic mapping knowledge and further competence. Also, this work will identify the main scientific and technological gaps and possible challenges for integrating the materials and fluids into existing systems and for maturation and large-scale feasibility for aerospace valorization and technology transfer enhancement.

“…31,32 These synergists are inert and non-toxic and do not release hazardous compounds during combustion, which makes them a perfect additive for sustainable biocomposites. 33,34 This study takes a new path in sustainability by introducing leather waste fibers as a resource in sustainable biocomposites. The waste fibers derive from the shaving process performed by the local leather industry in Leon, Mexico.…”

“…When looking at flame retardancy, synergists enhance certain modes of action that result in higher values for LOI, better UL 94 classification, or better performance in cone calorimetric measurements. , With synergists the load of flame retardant can be reduced, or better performance achieved with an equal loading. Synergism between silicon synergists and ATH has been reported for multiple systems. , One mode of action is the formation of a protective layer that can be enhanced by silicon-based synergists, for example, SiO 2 particles, − layered silicates (“nano clay”), − and low melting glass. , These synergists are inert and non-toxic and do not release hazardous compounds during combustion, which makes them a perfect additive for sustainable biocomposites. , …”

Nowadays, the hybridization of natural and glass fiber has promised several advantages as a green composite. Nevertheless, their different characteristics lead to poor mechanical bonding. In this work, agel fiber and glass fiber was used as reinforcements, and activated carbon filler was added to the polymer matrix of a hybrid composite to modify its characteristics and mechanical properties. A tensile and bending test was conducted to evaluate the effect of three different weight percentages of activated carbon filler (1, 2, and 4 wt%). Vacuum-assisted resin infusion was used to manufacture the hybrid composite to obtain the high-quality composite. The results have revealed that adding 1 wt% filler yielded the most optimum result with the highest tensile strength, flexural strength, and elastic modulus, respectively: 112.90 MPa, 85.26 MPa, and 1.80 GPa. A higher weight percentage of activated carbon filler on the composite reduced its mechanical properties. The lowest test value was shown by the composite with 4 wt%. The micrograph observations have proven that the 4 wt% composite formed agglomeration filler that can induce stress concentration and reduce its mechanical performance. Adding 1 wt% filler offered the best dispersion in the matrix, which can enhance better load transfer capability.
