The mechanical and thermal properties of polymer hybrid composite reinforced by rice husk ash at different conditions

Abstract EN

This research was carried out to study the effect of natural and calcined temperature of rice husk ash with selected temperature (900, 1100, 1300 oC) on the mechanical and thermal properties for the prepared hybrid composite with fixed volume fraction (25 % fiber glass, 5 % rice husk ash ).

The mecha nical properties include (tensile strength, bending strength, impact strength and hardness).

The results show that the mechanical and thermal properties increased with increasing the calcined temperature and the best calcining temperature of rice husk ash is 1300 oC, grinding rice husk before burning led to a decrease in mechanical properties and thermal conductivity.
