In this paper an experimental investigation of unsaturated polyester(UPR) with
different weight fractions(2,4,5,7 )wt% of (Al2O3,MgO,TiO2) as powders ,has been done.
the identification of their flammability and fire resistance ranges are found out
. the time
needed to puncture the samples, the mass loss, the diameter variation ,and the flame effect
on the samples surface are measured. the samples were tested by Oxyacetylene flame using
a device which is designed in the Faculty of Mechanical and Electrical Engineering labs.
The results showed that (MgO) is the best one for its flammability and fire
resistance. The longest time before puncture , and the lowest mass loss were achieved by(
UPR+ 7% MgO) with(16% mass loss in 112 sec ), while pure UPR has ( 27% mass loss in
45 sec).
