Summary

An experimental technique is proposed to determine quantitative fiber pullout energy at elevated temperature using a special 3-point bend specimen. Based on the quantitative measurements of the fiber pullout energy and fiber pullout length, the microfracture mechanisms for the fiber pullout and the frictional shear strength (τ0) at the fiber/matrix interface in a Cf/Si3N4-composite material are addressed.
