The role of cladding in the mechanical properties of SiC-fiber reinforced Ti-matrix composites (TMCs) has been examined. Experimental and analytical results obtained on model clad panels are reviewed. A case study was conducted by taking the example of TMC connecting rod which utilizes the cladding principle for design of a high stiffness component. Experiments on specimens which mimic real components were conducted in an attempt to identify design-limiting factors. Results suggest that the elastic properties and strength of the clad TMCs can be modeled using modified rules of mixtures. Fatigue life of the component was lower than expected and a brittle reaction layer was identified as the source for crack initiation under fatigue and hence lowered fatigue life.
