An Experimental Study on Toughening of Unsaturated Polyester Mortar Using Polyuretane Liquid Rubber

폴리우레탄 액상고무를 이용한 불포화 폴리에스테르 모르터의 인성개선에 관한 실험 연구

The purpose of this study is to investigate toughening of unsaturated polyester resin by addition of polyuretane liquid rubber. In general, unsaturated polyester resin has strong brittleness in spite of its high strength Therefore; it is difficult to use unsaturated polyester mortar for the place where impact resistance is demanded. In this study, it was evaluated strength and Gf by using to polyurethane liquid rubber. As a result, the toughness of unsaturated polyester mortar was increased by polyuretane liquid rubber.
