الملخص EN

In this research alumina and titanium powders were used with different volume fractions (0 %, 5 %,10 and15 %) to produce composite material.

Several tests were conducted such as wear, impact, compressive strength and Brinell hardness for unsaturated polyester reinforcement with titanium or alumina powder.

Reduction in wear rate was recognized with increasing the volume fraction from 26 to 6 gm/cm and from 26 to 4.5 gm / cm for unsaturated polyester reinforced with alumina and titanium respectively.

The highest impact resistance obtained at volume fraction 10 % were 14 and 12 KJ / m3 for specimens reinforced with titanium and alumina respectively.

Also the compressive strength gave the highest values at 10 % volume fraction which where 229 and 180 MPa for alumina and titanium respectively, while the hardness founded increased with volume fraction increasing the value obtained at 15 % volume fraction were 15 and 12 for titanium and alumina respectively.

Unsaturated polyester reinforced with alumina showed more wear resistance and compressive strength while unsaturated polyester reinforced with titanium gave high hardness and impact strength comparison with alumina.
