| Abstract: | By using epoxy resin and thermoplastics resin to modify cyanate ester resin,a modified cyanate ester resin adhesive film for bonding advanced radomes was developed.Conversion rate of —OCN groups was determined by FTIR spectra after curing.The adhesive film is of desirable process adhesion and its shelf life is 20 days at ambient temperature.Lap shear strength of the adhesive film at 200℃ is larger than 15 MPa.Under the frequency of 9.375 GHz,dielectric constant of the adhesive film is 3.09,and dielectric loss tanδ is 0.014. |
