文摘The influences of various kinds of UV-absorbers, antioxidants and their mixtures on UV-aging resis- tance of transparent unsaturated polyester FRP are studied by artificial aocelerating aging test.The results show that the UV-aging resistance of com- bined stabilizers is better than single stabilizer. It is concluded that the cooperative effect of UV -absorbers is caused bg the increase of wave leng- th and intensity of the absorption light the coopora- tive effect of UV-absorbers and antioxidants is caused by Dreventing the photo-oxidantion.
