Abstract
A carbon/silica composite (composite) fabricated from agricultural waste of rice husk (RH) without using any binders. In the present study, the effect of heating temperature on the mechanical and material properties of the composite was investigated. The slab-shaped composites heated to 300, 500, 800, 1000, and 1200°C were prepared and their mechanical properties such as bulk density and compressive strength were evaluated. The composites heated to 1000°C displayed the highest bulk density and compressive strength, which were respectively 1.25 g/cm3 and 203.4 MPa. It was revealed that the composites were subjected to thermal shrinkage of the matrix material derived from RH. The thermal shrinkage led to a densification of the composite, improving the mechanical properties.
