The yarn size dependence of tensile and in-plane shear properties of three-dimensional needled textile reinforced ceramic matrix composites
Highlights Large yarn size causes the nonwoven yarn crimp for 3DN CMC. Large yarn size results in decrease of the tensile and in-plane shear properties. Modified lamina modeling predicts two moduli of 3DN CMC with different yarn size. Other two methods well predict two strengths of 3DN CMC with different yarn size.
Abstract The yarn size scaling of tensile and in-plane shear properties is examined for three-dimensional needled textile reinforced ceramic matrix composites (3DN CMC) fabricated by chemical vapor infiltration. The results showed that large yarn size would cause the nonwoven yarn of 3DN CMC crimp and lower composite density, resulting in decrease of tensile and in-plane shear properties. The “modified lamina modeling” was presented to predict the tensile and shear elastic moduli of 3DN CMC with different yarn size. Other two methods were also proposed to evaluate the tensile and in-plane shear strengths of 3DN CMC with different yarn size, respectively. All predicted results showed consistent well with the experimental results.
