Michael Braksiek,Kinga Golus,Lilian Streblowield of the sol using a particulate filler. After sintering the composites were found to be microcracked as a result of the constrained sintering and thermal shrinkage. The interfacial shear strength has been estimated from the average spacing of the microcracks, and found to be comparatively low fo

Peter Schildhauer,Carolin Zehneors were optimized with respect to ceramic yield and minimum bloating during pyrolysis. Solution infiltration of stacked Nicalon SiC fibre weaves was performed. Repeated impregnations/pyrolyses yielded fairly strong composites exhibiting non-brittle fracture behaviour, especially when a polymer free

https://doi.org/10.1007/978-3-658-34178-7l composite SiC/SiC and C/SiC materials combine a good resistance to oxidation and to chemical agressions with a high mechanical behaviour, at high temperature and an exceptional toughness-compared to the classical ceramics. News applications have been found for these new composites in the fields of

Applications of Transmission Electron Microscopy for the Study of Composites (Carbons-Sic) RelationsPeculiar modes of TEM allowing to restitute the three dimensional arrangement of elementary scattering domains (microstructure) of a given material are described. Applications to carbon and ceramic (SiC) fibres and matrices are given as examples. Mechanical and electrical properties related to microstructure are considered mainly for carbon fibres.
