Fiber‐reinforced aerogels are a class of reinforced aerogels characterized by very low thermal conductivity, hydrophobicity and most importantly load bearing capability. In this work, an experimental study describing the damage in these fiber‐reinforced aerogels through various uniaxial compression tests is presented. While understanding the damage evolution at the micro‐scale, we come across three probable sources contributing towards the damage evolution. They are: (a) matrix cracks, (b) debonding of particles due to fiber sliding, and (c) breakage of fibers. (© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
