摘要
首先对三种规格的国产芳纶Ⅲ纤维F-3/23 tex、F-3/44 tex和F-3/135 tex性能及其对应织物F-3P60、F-3S120和F-3S175性能进行了分析讨论。其次采用热熔预浸及热压罐固化法制备了三种国产芳纶Ⅲ织物/3233中温环氧复合材料F-3P60/3233、F-3S120/3233和F-3S175/3233,通过层合板复合材料的拉伸、压缩、弯曲、剪切性能及夹层板复合材料的滚筒剥离性能测试,获得了三种织物复合材料较为全面的基本性能,并对低温、湿热和水煮条件下的芳纶Ⅲ织物复合材料性能进行了测试并和室温性能进行对比分析。结果显示F-3/23 tex、F-3/44 tex和F-3/135 tex纤维的断裂强度均可稳定在28.7 cN/dtex以上;F-3P60、F-3S120和F-3S175织物的拉伸断裂强度较高,其中F-3S175的经向、纬向拉伸断裂强度达到4499 N/25 mm和4338 N/25 mm,较进口914织物分别提高81.7%和47.5%;F-3P60/3233、F-3S120/3233和F-3S175/3233复合材料性能稳定,湿态条件的压缩强度降低幅度依次为41.6%、41.0%和40.5%,水煮条件层间剪切强度依次降低31.4%、35.3%和31.6%。
The properties of domestically produced aramid fibersⅢ(F-3/23 tex,F-3/44 tex and F-3/135 tex)and their corresponding fabrics(F-3P60,F-3S120 and F-3S175)are analyzed and discussed.And then the aramidⅢfabrics/3233 intermediate temperature curing epoxy composite materials(F-3P60/3233,F-3S120/3233 and F-3S175/3233)are prepared by hot-melt prepreg and autoclave curing methods.By testing the tensile,compression,bending and shear properties of laminated composite materials and the climbing drum peel properties of sandwich plate composites,the more comprehensive basic properties of the three kinds of fabric composite materials are obtained.Then the properties of aramidⅢfabric composites under conditions of low temperature,damp heat and water-boiling are also tested and compared with the properties under room temperature.The results show that the fracture strengths of F-3/23 tex,F-3/44 tex and F-3/135 tex fibers can be stabilized above 28.7cN/dtex.The tensile fracture strengths of F-3P60,F-3S120 and F-3S175 fabrics were relatively high,among which the meridional and zonal tensile fracture strengths of F-3S175 reached 4499 N/25 mm and 4338 N/25 mm,which are 81.7%and 47.5%higher than imported 914 fabrics respectively.The properties of F-3P60/3233,F-3S120/3233 and F-3S175/3233 composites were stable.Their compression strengths in wet state decreased by 41.6%,41.0%and 40.5%respectively,and their interlaminar shear strengths in water-boiling condition decreased by 31.4%,35.3%and 31.6%respectively.
