ABSTRACT

The kinetics of loss of mechanical properties in fique and cotton fibers impregnated in vacuum were evaluated as substitution alternative to the polypropylene fiber in the vertical support of the pea crop. The results were compared with non-impregnated fique fibers, non-impregnated cotton and polypropylene. The impregnation of vegetable fibers was carried out at 0.2 bar at 15°C for 2 min under vacuum. The fibers studied were implemented in culture, evaluating weekly their mechanical properties for 13 weeks. The impregnated fique presented a lower mechanical loss rate compared to the fique without impregnation in tensile strength, total elongation at maximum force and Young’s modulus. The impregnated cotton had a lower mechanical loss rate compared to the non-impregnated cotton in Young’s modulus. The speeds of mechanical loss in the three properties evaluated in polypropylene are comparable with fique and impregnated cotton.

摘要

在真空中浸渍的纤维和棉纤维的机械性能损失动力学被评估为豌豆作物垂直支撑中聚丙烯纤维的替代品。将结果与未浸渍的纤维、未浸渍的棉和聚丙烯进行比较。植物纤维的浸渍在 0.2 bar 和 15°C 下真空进行 2 分钟。研究的纤维在培养中实施，每周评估其机械性能，持续 13 周。与未浸渍的纤维相比，浸渍的纤维在拉伸强度、最大力下的总伸长率和杨氏模量方面表现出较低的机械损失率。与未浸渍的棉花相比，浸渍的棉花在杨氏模量方面具有较低的机械损失率。
