Towards an aerogel-based coating for aerospace applications: reconstituting aerogel particles via spray drying

Effect of different weightage of Enova® IC3100 silica aerogel on aluminium alloy composites in ISO2685 aviation standard fire-test

“…Various types of composite materials were used in the fabrication of new aircraft generation components which include carbon fibre reinforced plastic and fibre metal laminates composites, but its main problems are weight and delamination by using so many layers (Mohammed et al, 2017;Sikoutris, 2012;Tranchard et al, 2015). To avoid delamination due to thermal shock and a reduced weight, a greener material is required for a component of such locations (Bheekhun et al, 2016).…”

Macroporous Polyimide Aerogels: A Comparison between Powder Microparticles Synthesized via Wet Gel Grinding and Emulsion Processes

“…Powder particles can be made using a variety of techniques, including spray drying, − an emulsion process, − jet-cutting, − and dry milling methods in which the powder is obtained using mechanical means such as milling or crushing of previously formed monolithic aerogel structures. , However, irrespective of how they are made, these types of powders have been shown to exhibit weak mechanical properties . Concerning this, Lee et al detailed the process of using swelling methods to manufacture polyimide aerogel spherical formation.…”

Feasibility of incorporating silica aerogel in atmospheric plasma spraying coatings

“…Applying an experimental design to the atomisation process, Bheekhun et al tried to optimise the atomisation conditions in order to obtain granulated silica powders that could be used in plasma spray. The atomisation was performed using different mixtures of silica aerogel with Y-TZP, obtaining granulated powders that, a priori, could be successfully sprayed, although they did not manufacture coatings with these granulated powders [24]. In a similar work, Mohd-Zulkifli et al dealt with the atomisation of aerogel samples [25], in this case without mixing with any other material, with a view also to their application in thermal spraying coatings, obtaining agglomerated powders that did not spray either.…”
