Natural fiber reinforcements have the potential to enhance mechanical properties, thereby improving performance and durability in various applications. In this study, we comprehensively evaluated the impact of environmental degradation over 120 days on reprocessed polypropylene (PP) reinforced with corn husk fiber (CHF) composites. The manufactured systems underwent rigorous analysis using various techniques, including Fourier transform infrared spectroscopy, thermogravimetric analysis, optical microscopy, scanning electron microscopy, and tensile testing. These analyses revealed that climatic conditions significantly influenced ( < 0.05) the mechanical properties of all systems. Photodegradation led to surface morphological changes and chemical structures. Regardless, adding CHF filler proved a key factor, as it allowed for less susceptibility to environmental degradation than the reprocessed matrix. These findings, therefore, provide robust evidence supporting the feasibility of using CHF composites for manufacturing agricultural containers.
天然纤维增强材料有潜力提升机械性能，从而在各种应用中提高性能和耐用性。在本研究中，我们全面评估了环境降解120天对用玉米 husk 纤维（CHF）增强的再生聚丙烯（PP）复合材料的影响。所制造的系统使用多种技术进行了严格分析，包括傅里叶变换红外光谱、热重分析、光学显微镜、扫描电子显微镜和拉伸测试。这些分析表明，气候条件对所有系统的机械性能有显著影响（<0.05）。光降解导致表面形态变化和化学结构改变。尽管如此，添加CHF填料被证明是一个关键因素，因为与再生基体相比，它对环境降解的敏感性较低。因此，这些发现提供了有力证据，支持使用CHF复合材料制造农用容器的可行性。
