Mechanical behavior of ZTAp/40Cr three-dimensional interpenetrated composites under compression

Abstract We used a hierarchical algorithm to study the mechanical behavior of the ZTAp/40Cr three-dimensional (3D) interpenetrating composite under uniaxial compressive force. First, we developed a microscopic uniformly distributed representative volume element (RVE) model to measure the properties of the ZTAp/40Cr 3D interpenetrating composite under uniaxial compression. We studied the effect of the interfacial parameters on the properties of homogeneous composites. Furthermore, we equated the properties measured using microscopic uniform distribution RVE model with the 3D interpenetrating composite zone properties to analyze the power, durability, and harm modes of the 3D interpenetrating composites with 35% and 50% volume fraction in the composite zone. We observed that the interface strength and fracture energy significantly influence the compression properties of the composite. Moreover, the simulations for the macroscopic 3D interpenetrated composites are consistent with the experimental structural mechanics. Our findings can serve as a foundation for further research on the properties of 3D interpenetrated conformal composites.
