摘要

制备了芳纶短纤维增强高密度聚乙烯杂化复合装甲,研究了微纳填料的加入对装甲动态冲击响应和弹道冲击吸能的影响。采用高密度聚乙烯和增强材料混合的球团压缩成型制造了五组样品。第一组由高密度聚乙烯与10 wt%凯夫拉纸浆(KN-1)增强组成。其余的是混合复合材料,添加20%的微纳米填料。使用的天然微填料是chonta棕榈木(KN-2)和马铃薯粉(KN-3)的颗粒。合成的纳米填料是胶体二氧化硅(KN-4)和γ -氧化铝(KN-5)。对复合材料的微观结构(扫描电镜)和成分(能量色散光谱)进行了分析,对基体-增强-界面进行了评价。制备的复合材料板采用分离式霍普金森压力杆系统进行高速冲击和弹道冲击,根据NIJ标准- 0101.06进行弹道阻力测试。将合成纳米颗粒添加到凯夫拉纤维增强高密度聚乙烯中,可显著改善高达43.5%的刚度。x射线衍射分析表明,添加纳米粒子作为填料对凯夫拉增强高密度聚乙烯的晶体结构没有影响。然而,晶体峰的强度随添加填料的类型而降低。采用分离式霍普金森压杆进行动态冲击试验,结果表明,添加合成纳米填料(二氧化硅和氧化铝)可提高材料的抗冲击性。弹道冲击试验结果表明,γ -氧化铝纳米颗粒(KN-5)具有最高的能量吸收能力。结果表明,掺加微纳米填料的杂化芳纶短纤维增强高密度聚乙烯增强了复合材料的刚度、抗冲击性能和弹道吸能能力。图形抽象

The Effects of Micro- and Nano-Fillers’ Additions on the Dynamic Impact Response of Hybrid Composite Armors Made of HDPE Reinforced with Kevlar Short Fibers
ABSTRACT Hybrid composite armors consisting of Kevlar short fibers reinforced high-density polyethylene were prepared and the effects of the addition of micro and nano-fillers on the dynamic impact response and the energy absorption under ballistic impact were investigated. Five groups of specimens were manufactured using compression molding of pellets containing mixtures of high-density polyethylene and the reinforcing materials. The first group consist of high-density polyethylene reinforced with 10 wt% Kevlar pulp (KN-1). The rest are hybrid composites created by the addition of 20 wt% of micro and nano-fillers. The natural micro-fillers used are particles of chonta palm wood (KN-2) and potato flour (KN-3). The synthetic nanofillers are colloidal silica (KN-4) and gamma alumina (KN-5). Microstructure (scanning electronic microscope) and compositional (energy-dispersive spectroscopy) analysis of the hybrid composites were carried out to evaluate matrix-reinforcements-interface. The fabricated composites plates were subjected to high velocity impact using split Hopkinson pressure bar system and ballistic impact, according to NIJ standard–0101.06 for ballistic resistance. Significant stiffness improvements of up to 43.5% were achieved as a result of the addition of synthetic nano-particles to Kevlar fiber reinforced high-density polyethylene. X-ray diffractometer analysis revealed that the crystalline structure of the Kevlar reinforced high-density polyethylene is unaffected by addition of the nano-particles as fillers. However the intensity of the crystalline peaks decreased depending on the type of the added fillers. The results of dynamic impact test using split Hopkinson pressure bar revealed improved impact resistance by addition of synthetic nanofillers (silica and alumina). The results of the ballistic impact test showed the gamma alumina nano-particles (KN-5) exhibited the highest energy absorption capability. The results of these investigations indicate that hybridization Kevlar short fibers reinforced high-density polyethylene by micro and nano-fillers addition enhances the stiffness, impact resistance and ballistic energy absorption capability of the composites.
