Abstract

An SEM quantitative stereophotogrammetry technique was developed and employed to analyse the fracture surfaces of VLS SiC whisker-Si3N4 matrix composites. This technique has quantitatively established that increased surface roughness is associated with increased fracture toughness for these composites. Matrix grain morphology and whisker/matrix interfacial characteristics are contributing factors to composite surface roughness.
