A Study on the Development and Properties of a 150 ℃ Resistant Reticulation Epoxy Adhesive Film
A 150℃resistant reticulation epoxy adhesive film is prepared,which is moderately sticky,and can be spread easily on the surface of the honeycomb core for reticulation.After reticulation,the film forms uniformly distributed fillet on the end of the honeycomb core.The glass transi-tion temperature of the adhesive film is measured to be 153.3℃.The adhesive film exhibits excellent mechanical properties with lap shear strength of 37.2 MPa at room temperature and 17.4 MPa at 150℃.The climbing drum peel strength of the reticulated adhesive film is 115.6%higher than that of the unreticulated film.The adhesive film is developed for bonding carbon-fiber mesh panels or perforated panels to honeycomb cores.
