The effect of Cu content on the microstructure and properties of Cf/ZrC composite ceramics were investigated.
Based on this, Ni was added into the complex to prevent the chemical injury of carbon fiber by Deng Qichao[6], leading to the production of (Ni,Cf)/TiC-TiB2 composite ceramics with excellent mechanical properties.
We conclude that because the strength of the composite ceramics is a very sensitive quantity which can be influenced by many factors.
Under the certain of components, porosity and phase components are the two key factors.
Of note, the substrate of the material plays key roles in affecting the strength of the Cf/ZrC-xCu strength ceramic composites.

A finite element model was developed in this research to investigate the impact of defects on the mechanical properties of a 3D-printed composite sandwich panel that could occur during the layer alteration period between the dissimilar materials, affecting the interfacial strength between the layers and causing the 3D-printed panel to fail.
Numerous parameters, such as interfacial position, size, material properties, and location of defects along the panel, have been examined that might affect the failure mechanism.
The endpoints where we have support responses have significant maximum shear stresses, which could degrade the material overall mechanical properties.
These findings help explain how flaws affect the mechanical characteristics of sandwich panels and how the position, shape, and inclusion of material factors affect mechanical responses [14].
Numerous factors, including as the position of the flaws along the panel, size, characteristics, and interfacial area, have been researched as factors that may affect the failure mechanism.
