Anotace knihy

Silica aerogel are highly porous nanostructured solids materials with wide range of applications. However silica aerogels are inherently fragile and brittle. Thus, their use in load-bearing applications presents a challenge. In this book, mechanical behavior of nanostructured silica aerogel is characterized under compression and three-point bending tests. In order to develop a better understanding of the synergistic stiffening and strengthening mechanism of the crosslinker a numerical model was developed using Particle Flow Code ®. The compressive strength increased 40 times the strength of plain silica aerogels. Testing was also carried out under different strain rates and temperatures. In flexural tests the stress-strain curve obtained showed a perfect elastic behavior and the \"conchoidal\" fracture morphology. The results from numerical modeling emphasis need for a better algorithm that can generate the silica aerogel structure. Also the quantitative parameters determined from modeling need to be experimentally validated.
