Ceramic Matrix Specific Modulus

Ceramic matrix composites cmcs have the advantages of low density high specific strength high specific modulus and high temperature resistance etc and are the candidate materials for the hot section components of aerospace vehicles high.

Ceramic matrix specific modulus.

Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. Specific modulus last updated september 29 2019. It is also known as the stiffness to weight ratio or specific stiffness high specific modulus materials find wide application in aerospace applications where minimum structural weight is required. An attractive method to characterize the flexural modulus at room and high temperature under specific atmosphere is the nondestructive resonant frequency damping analysis rfda.

Ceramic matrix composites cmcs are a subgroup of composite materials as well as a subgroup of ceramics they consist of ceramic fibers embedded in a ceramic matrix. Wc is a chemical compound specifically a carbide containing equal parts of tungsten and carbon atoms. Tungsten carbide chemical formula. In its most basic form tungsten carbide is a fine gray powder but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery cutting tools abrasives armor piercing shells and jewellery.

Durability of ceramic matrix composites presents the latest information on these high temperature structural materials and their outstanding advantages over more conventional materials including their high specific strength high specific modulus high temperature resistance and good thermal stability. The homogeneous parallel alignment of flg works via a mechanism similar to that of rebar in concrete. The determination of elastic properties at application temperature is fundamental for the design of fibre reinforced ceramic composite components. The critical nature of the application of these advanced materials makes it necessary to.

The critical nature of the application of. Both the matrix and the fibers can consist of any ceramic material whereby carbon and carbon fibers can also be considered a ceramic material. While the data in these charts is in most cases typical of what you will find from ceramic component suppliers it is only intended to be a general point of reference and should not be used for material selection or specification. Graphenes with a high young s modulus strength and large specific area are well dispersed in the ceramic matrix transferring the load from the matrix which notably improves the composite flexural strength 42 46.
