These resins are involved beneficial proprieties such as high modulus and strength, their physical and mechanical properties are shown a good resistance against high temperatures due to their stiffness and the high density of their cross link. The obtained results show that with adding Acrylonitrile Butadiene Styrene (ABS) decreases tensile strength and modulus, and increases the percentage of elongation at break as well as the toughness of UPRs. As observed in the bending test , the maximum bending reaches to 4.460 MPa and for tensile test the maximum reaches to 63.217 MPa .The morphological analysis of Acrylonitrile Butadiene Styrene on heated composites shows a two-phase system which causes rubber particles to be dispersed in resin matrix. This study introduces Acrylonitrile Butadiene Styrene in order to investigate physical, mechanical , and morphological properties on unsaturated polyester resins. As unsaturated polyester resins resistance against cracking and toughness is low, in order to overcome in these disadvantages, Acrylonitrile Butadiene Styrene was added and mentioned disadvantage largely improved.
