A medium-temperature wave-transparent and self-adhesive resin was developed while the gel time and rheological properties were tested.Glass fiber fabric and quartz fiber fabric reinforced epoxy resin prepregs were prepared using the medium-temperature wave-transparent & self-adhesive resin, and the physical properties were characterized at the same time.The heat-resistance,mechanical properties and dielectric property of composite laminates were studied.The results show that the glass-transion temperature of composites is 148℃; the composites have good mechanical properties and excellent dielectric property;and the 93℃ mechanical properties are good.The prepreg were bonded with honeycomb material without coating.The roll peel strength of honeycomb sandwich was tested. The results show that the roll peel strength of≥50N.mm/mm satisfies with application requirements.Compared with typical imported prepreg system of civil aircraft- CYCOM7701/7781,the room temperature and 93℃ short-beam shear strength performances of two kinds of composites are equivalent, and ACTECH1210/2221 is better in dielectric property and heat-resistance.
