In the context of different applications, advanced, high-performance structures can be produced through making use of the opportunities delivered by new processing routes and materials. Markedly, one such promising material is that of CMCs, i. Through joining together various ceramic matrix materials alongside appropriate fibres, there can be the creation and customisation of new properties for use in technical fields. One of the most important of advantages offered by CMCs is their natural resistance to high temperatures.
"Residual Strength of Metal Particulate Reinforced Ceramic Matrix Compo . . ." by Yu Fu
Damage accumulated continuously for both lay-ups, leading to eventual failure and a reduced fatigue life. Critical damage in the cross-ply consisted of longitudinal cracks in the 90 deg plies growing and combining with transverse cracks to effectively eliminate the 90 deg plies' load carrying capability and allowing the specimen to buckle. Critical damage in the unidirectional lay-up consisted of longitudinal cracks which initiated at the shear stress concentration points on the hole periphery. Reversed cyclic loading caused continued crack growth at maximum stresses below the tension-tension fatigue limit. The cross-ply lay-up appeared insensitive to the hole, while critical damage in the unidirectional lay-up was dependent on the shear stress concentrations at the hole Ceramic matrix composite, Tension-compression fatigue, Notched specimen. Similar records in OSTI.

On 12th June , Marion Broutelle defended her thesis. The purpose of this thesis is to analyse the mechanical behavior of bolted joints made of oxide-based CMC Ceramic Matrix Composites. It is part of a project aiming at developping and characterizing CMC with a new process less expensive than the former ones.
