Description
Summary:Biomimicking of woods has been conducted extensively in the past. In this work, the unique microstructural feature of maize stems has been explored. These stems appear to be promising precursor materials for producing fiber‐reinforced composites with unique anisotropic properties. A unique melt infiltration technique has been adopted to mineralize this structure into ceramic composites. The cellular morphology of the precursor stem was retained in the final composite. SiC–Si and MoSi2–SiC cellular composites were obtained by infiltration with Si and Si–MoSi2–Al mixture, respectively. It has been found that a small (2 wt%) addition of aluminum in the infiltrating mixture can help in attaining a homogeneous distribution of MoSi2 in the SiC cellular matrix.
