中文摘要:研制一种新型高韧性高温环氧树脂ACTECH 1316体系,研究其固化反应特性、流变性能及耐热性能,其中Tg可达222.5℃,可在130℃温度下长期使用。分别选用两种国产碳纤维CCF800H和ZT9H作为纤维增强体,通过热熔两步法制备预浸料,加工工艺性较好,显示出该树脂体系与两种纤维有较好的匹配性。采用热压罐工艺进行固化,对复合材料层合板的力学性能进行研究,通过与国外高温环氧树脂体系8552/IM7的性能对比发现,ACTECH 1316/ZT9H和ACTECH 1316/CCF800H在0°拉伸强度及模量、0°压缩强度及模量和冲击后压缩强度等方面表现较好,基本满足民机领域对树脂及复合材料性能的要求。
英文摘要:A new high toughness and elevated-temperature epoxy resin system ACTECH 1316 was designed. After analyzing its curing reaction characteristic, rheological property and heat-resistant quality, the resutts showed glass transition temperature was 222.5℃ and was able to be used at the temperature of 130℃ chronically. Two kinds of domestic fiber reinforcement, such as CCF800H and ZT9H, were selected to prepare prepreg respectively by using hot melt two-step process which had excellent manufacturing process, showed good compatibility with two carbon fiber systems. Autoclave process was used to solidify prepreg, and the mechanical properties of composite laminated plates were studied, which showed better properties. Compared with the performance of high-temperature epoxy resin 8552/IM7 prepreg from abroad, 0°tensile strength and modulus, 0°compression strength and modulus and the compression strength after impact of ACTECH 1316/ZT9H and ACTECH 1316/CCF800H could meet the basic requirement for resin and composite materials in civil aviation field.
