Rocket engine insulation layer - foamed aluminum surface enhancementFoamed aluminum has excellent thermal insulation performance - but its mechanical performance structure is fragile, and there are a lot of cracks and microporous structures on the surface and between the blocks. The addition of perhydropolysilazane resin not only fills the gaps and improves the mechanical strength of foamed aluminum, but also improves the performance of the overall composite material in many aspects as an excellent thermal insulation, flame retardant and heat-resistant material after curing.
