الملخص EN

In this paper, several specimens from unsaturated poly ester resin with different filler materials such as (Fe2O3, CaCO3, CaO, Cement, Ca(OH)2( have been prepared.

Three weight percent have been used as (10%,20%, and 30% wt)from each filler materials.

Casting samples are grinded by 800 grit using SiC grinding paper and then washed by distilled water.

Dry sliding wear has been done using pin on desk test in different period of wear time as (5,10,15,20,25,30 min).

it has been shown that addition of cement with percent (10 % wt) get lower wear rate for unsaturated polyester resin.
