Abstract

Thermal residual stress (TRS) created in metal matrix composite influences the mechanical properties of composites. In this paper, we present the TRS-modulated tensile properties of continuous SiC fiber reinforced titanium (SiC/Ti) composite. The magnitude and distribution of TRS inside SiC/Ti were evaluated by using a simple 1-D beam model considering fiber-matrix structure and then a full 3-D FEM model. The bending of the SiC/Ti specimen resulting from the asymmetrical fiber placements was used as a measure to verify the pertinence of the mechanical models. A 3-D FEM simulation accounting all TRS information gives a good prediction of the composite’s tensile properties.
