..., the matrix transmits loads from the matrix to the fibers through shear loading at the interface. In ceramic-matrix composites, the objective is usually to increase the toughness rather than the strength and stiffness, and a low-interfacial-strength bond is therefore desirable. The type and quantity...

... Abstract Ceramic-matrix composites possess many of the desirable qualities of monolithic ceramics, but are much tougher because of the reinforcements. This chapter explains how reinforcements are used in ceramic-matrix composites and how they alter energy-dissipating mechanisms and load...

... Abstract Ceramics normally have high melting temperatures, excellent chemical stability and, due to the absence of conduction electrons, tend to be good electrical and thermal insulators. They are also inherently hard and brittle, and when loaded in tension, have almost no tolerance for flaws...

... with the maximum loads available. Closed-die forgings are produced by forging ingots, plates, or extrusions between a matched set of dies. Closed-die forging uses progressive sets of dies to gradually shape the part to near-net dimensions. Die forgings can be subdivided into four categories from the lowest...

Due to the strength and stiffness advantages of fibers, they are the predominant reinforcement for advanced composites. Fibers...
