An innovative model studies tensile behaviors in carbon fiber minicomposites, revealing complex stress dynamics.
Understanding the constitutive behaviors of minicomposites is critical in the multi‐scale study and very important to prepare and evaluate the advanced ceramic matrix composites. In this work, an innovative method for testing the tensile behaviors of minicomposites is developed based on the induction heating technology. A theoretical model for the tensile stress–deformation behaviors of minicomposites is developed by characterizing the complex dynamic stress distributions of bonded and debonded zones innovatively. C/PyC/SiC minicomposites are fabricated by depositing PyC interphase on the exterior of carbon fiber bundles followed by infiltrating the SiC matrix. The tensile constitutive behaviors of C/PyC/SiC minicomposites are studied up to 1800°C in argon atmosphere. Significant nonlinearity and “sawtooth” features of the constitutive curves are observed in the experiments and characterized by theory. The results provide new insights into the deformation and fracture behaviors of advanced ceramic matrix composites.
