中文摘要:研制了一款中温透波自黏性树脂,对树脂的凝胶时间、流变性能等进行了测试,使用该树脂制备了中温透波自黏性玻璃纤维织物及石英纤维织物预浸料,对预浸料的物理性能进行了表征测试。研究了复合材料层合板的耐热性、力学性能和介电性能,结果表明复合材料玻璃化转变温度达148℃,具有优良的力学性能和介电性能,且在93℃时具有较高的力学性能保持率,满足使用要求。进行预浸料和蜂窝胶接,测试了试验件的剥离强度,结果表明滚筒剥离强度≥50N.mm/mm,树脂预浸料自黏性较好,夹层结构的滚筒剥离强度高 ,满足应用指标要求。与民机用典型进口预浸料体系CYCOM7701/7781对比,两种复合材料室温干态及93℃干态层间剪切性能相当,ACTECH1210/2221在耐热性与介电性能方面更具优势。
英文摘要: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.
