Pullout of metallic fibres in a ceramic refractory matrix

IPCM7 - 7th international conference on interfacial phenomena in composite materials, 11-14 september 2001, Arcachon, FRANCEInternational audienceThe extraction behaviour of stainless steel fibres from a ceramic refractory matrix has been studied by way of pullout tests and scanning electron microscopy observations. The effect of first heating of such composites has been characterised both by room temperature pullout tests and by dilatometric experiments. High temperature pullout tests have been performed too. Mechanical and microstructural evolutions are discussed with the help of analytical models
