This research aims to determine the mechanical properties of sugar palm fiber ( Wurmb. Merr) (SPF)/glass fiber (GF)-reinforced poly(lactic acid) (PLA) hybrid composites for potential use in motorcycle components. The mechanical (hardness, compressive, impact, and creep) and flammability properties of SPF/GF/PLA hybrid composites were investigated and compared to commercially available motorcycle Acrylonitrile Butadiene Styrene (ABS) plastic components. The composites were initially prepared using a Brabender Plastograph, followed by a compression molding method. This study also illustrated the tensile and flexural stress-strain curves. The results revealed that alkaline-treated SPF/GF/PLA had the highest hardness and impact strength values of 88.6 HRS and 3.10 kJ/m, respectively. According to the results, both alkaline and benzoyl chloride treatments may improve the mechanical properties of SPF/GF/PLA hybrid composites, and a short-term creep test revealed that the alkaline treated SPF/GF/PLA composite displayed the least creep deformation. The findings of the horizontal UL 94 testing indicated that the alkaline-treated SPF/GF/PLA hybrid composites had good flame resistance. However, alkaline-treated SPF/GF/PLA composites are more suitable materials for motorcycle components.
本研究旨在确定糖棕纤维(Wurmb. Merr)(SPF)/玻璃纤维(GF)增强聚乳酸(PLA)混杂复合材料的力学性能,以用于摩托车部件。研究了SPF/GF/PLA混杂复合材料的力学性能(硬度、压缩强度、冲击强度和蠕变性能)及燃烧性能,并与市售摩托车丙烯腈-丁二烯-苯乙烯(ABS)塑料部件进行了比较。复合材料最初使用布拉本德塑化仪制备,随后采用模压成型法。本研究还给出了拉伸和弯曲应力-应变曲线。结果表明,碱处理后的SPF/GF/PLA硬度最高,为88.6 HRS,冲击强度值最高,为3.10 kJ/m。结果表明,碱处理和苯甲酰氯处理均可改善SPF/GF/PLA混杂复合材料的力学性能,短期蠕变试验表明,碱处理后的SPF/GF/PLA复合材料蠕变变形最小。水平UL 94测试结果表明,碱处理后的SPF/GF/PLA混杂复合材料具有良好的阻燃性。然而,碱处理后的SPF/GF/PLA复合材料是更适合用于摩托车部件的材料。
