Effect of ageing at 1200 degrees C in oxidative environment on the mechanical response of SiOC foams
Original language description
Polysiloxane resin was used for development of light weight high temperature resistant foams using the starch foaming technique. The porosity was obtained in the range from 80% to 90%. The pore size effect on the elastic properties was determined and theobtained results were explained with the help of FEM simulation of model situations. The effect of ageing at 1200 degrees C in air on the density and mechanical properties was determined. The ageing changed slightly the density of foams. The elastic modulus decreased by 15% for the dwell time of 2 h. The extension of the dwell time had no additional effect. The compressive strength related to the density keeps the same trend when ageing is applied. The differences between as received and aged microstructure of foams were explained using SEM analysis.
