دراسة و استقصاء السلوك الميكانيكي و الحراري لمادة مركبة مقواة برماد قشور الرز

Abstract EN

The aim of this work is to prepare a nano-composite material from unsaturated polyester resin(UPS) filled with nano-rice husk ash (Nano-RHA)and study its mechanical and thermal properties.

Samples were prepared with three percentage weight ( 2,6,10%) of nano-RHA.

Dispersion by ultrasonic waves technique was used to disperse nano particles reinforcement within the matrix.

X-Rays diffraction technique had used to investigate the resulted material after combustion, the results show that Silica (SiO2) was only found.

SEM study show that silica particles size range (100-500 nm) and it was dispersed uniformly and adhere strongly with the matrix and there was some agglomeration particles with size up to 1 µm.

Mechanical tests such as tensile, compression, bending, impact and hardness were performed and results show an improvement at 6% nano-RHA and then decreasing.

Coefficient of thermal conductivity test show very low value of coefficient of thermal conductivity ranged ( 1.3 – 1.8 )*10-10 w/m.co , therefore, the UPS-Nano RHA composites can be used in thermal insulation sheets industry.
