Abstract
Using the bisphenol E cyanate ester (BECE) and hydroxyl-terminated polyether sulfone (Mx) to co -modify novolac-cyanate ester (Novolac-CE) resin,and laminating with quartz cloth,a 400 ℃ temperature resistant and low dielectric loss supported structural adhesive film for bonding advanced radar radomes is developed.The results show that the impact toughness of Novolac-CE can be increased to 13 kJ/m2,and the contact angel decrease to 72.8° with the addition of suitable amount of BECE and Mx in Novolac-CE resin.The adhesion strength between the disposed quartz cloth by the KH550/ethonal solution and Novolac-CE can be 70％ higher than original quartz cloth,but the excessive KH550 is negative for the thermal resistance of film.The lap shear strength of the film is measured to be more than 5 MPa at 400 ℃,where it can be continuously used for 60 rain,the dielectric loss is 0.014 (10 GHz).The adhesive film has a shelf life of more than 15 days at ambient temperature and suitable tackiness,which can be applied as high temperature transparent materials关键词
