Simulation of Manufacturing Process Ceramic Matrix Composites •Ceramic matrix reinforced with continuous or discontinuous reinforcement •Reinforcement: – Whiskers, particles, fibers – Oxide and Non -oxide CMC •Eg: SiC w/Si 3N 4, C/C, C/SiC, SiC/SiC, Al 2O 3. Motivation - CMCs Demand • Increased T operation • Eliminate cooling. Silicon carbide fiber reinforced titanium matrix (SiC/Ti) composites offer lightweight, high strength replacement materials for superalloys in gas turbine engines and airframes. Titanium matrices tend to react with SiC and form reaction products that exhibit properties which are very different from the starting constituents.

Ferrotec Metal Matrix Si-SiC Composite Ceramic Material take advantage of various material mixes to deliver unique material properties and performance characteristics. The material properties of Silicon-Silicon Carbide metal matrix composites make it a good solution for parts that are free from surface defects. Abstract: As increasingly more SiC-SiC ceramic matrix composites (CMCs) are being used in the hot sections of gas-turbine engines, there is a greater need for in situ strain measurement in these harsh conditions. Thin-film strain sensors are ideally suited for this task since they have minimal mass and are nonintrusive. However, if the bulk piezoresistive properties of SiC-SiC .

The book is divided into two parts: Part I deals with the study of inelastic deformation in metal matrix composites, while Part II tackles the micromechanical aspects of metal matrix composites.

The articles discuss different aspects of these two topics ranging from purely theoretical treatments to extensive experimental investigations. However, the interface between matrix and inclusions has to be weak.

In the present study, a model system, Al 2 O 3 –Ti 3 SiC 2 composite, is used to demonstrate that the toughness of ceramic can also be enhanced by using the reinforcement with weak internal layers.

Using the detailed micromechanical model, Ti matrix composite was simulated following a Monte Carlo framework. These simulations yield the empirical strength distribution of the Ti matrix composite, and insights into the dominant failure mode. The latter allows the construction of a stochastic model of composite failure.

Metal matrix composites (MMCs) provide superior properties compared to monolithic materials. MMCs typically have superior strength and stiffness while reducing density. An MMC is a two-component material where high strength ceramic fibres such as silicon carbide (SiC) reinforce a strong and ductile metallic matrix.

Over the past 30 years, titanium metal matrix composites (Ti MMCs) have been under considerable development and evaluation for use in aircraft engine and airframe applications. For airframers, the high specific modulus of Ti MMCs has been the.
