摘要/Abstract

摘要： 为了探究四种洋麻/芳纶不同混纺比对其混纺织物增强复合材料力学性能的影响,对以环氧树脂为基体,精细化处理的洋麻和对位芳纶不同混纺比机织物为增强体的复合材料进行力学性能测试,并对洋麻纤维扫描电子显微镜(SEM)及傅里叶红外光谱(FTIR)测试分析纤维表面粗糙度及极性变化,从而来分析力学测试结果。结果表明,洋麻/芳纶30/70混纺织物增强复合材料弯曲强度最高,为248.81MPa,弯曲模量为12.91GPa,与纯芳纶织物增强复合材料相比,分别提高4.9%和7.1%;而洋麻/芳纶20/80混纺织物增强复合材料剪切强度最高,为24.58MPa,与纯芳纶织物增强复合材料相比,提高18.6%。SEM及FTIR表明洋麻纤维精细化处理后,纤维表面粗糙度增加,极性降低,提高了增强体与树脂的界面结合力,从而改善了复合材料的弯曲、剪切性能。

Abstract: In order to explore the effect of the four different blend ratios of kenaf/kevlar on the mechanical properties of blended fabric reinforced composites, the mechanical properties of composites reinforced by epoxy resin matrix, fine processing kenaf and aramid woven fabrics of different blending ratios were tested, and the morphology and polarity of kenaf fibre were examined by SEM and FTIR. The results show that kenaf/aramid 30/70 reinforced composites have the maximum flexural strength of 248.81MPa, and improved by 4.9%, flexura modulus of 12.91GPa, and improved 7.1%, compared with pure kevlar fabric reinforced composites. The maximum shear strength of kenaf/aramid 20/80 reinforced composites are 24.58MPa, increased by 18.6%. SEM and FTIR results indicate that the kenaf fiber became fine after treatment, fiber surface roughness was increased and the polarity became lower, which improves the interfacial bonding strength of the fabric with a resin, and improves the flexural and shear properties of aramid composites.
