This
research was carried out to study the effect of natural and
calcined temperature of rice husk ash with selected temperature
(900,1100,1300oC) 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 1300oC,
grinding rice husk before burning led to a decrease in
mechanical properties and thermal conductivity. |
