Effect of Aerogel Particle Concentration on Mechanical Behavior of Impregnated RTV 655 Compound Material for Aerospace Applications

Figure 8

Effect of PCSA particle size and concentration on the stress-elongation behavior of the compound material at 77 K. As IL increases from 25% (a) to 50% (b) and finally 75%, (c) the compound material becomes weaker rupturing under lower load values than the neat polymer. Effect of the particle size variation seems less significant than the IL.
