对气候变化和废物污染的日益关注正导致产品向绿色材料转变。汽车行业正在探索玻璃纤维（GF）的环保替代品。本研究的重点是了解由玄武岩纤维（BF）和大麻草颗粒纤维（HF）增强聚丙烯（PP）的生物复合材料的组分之间的相互作用，并统计比较力学性能。偶联剂的加入显著改善了生物复合材料共混物的性能和纤维-基质相互作用。一些BF/HF/PP混合物的弹性模量与GF/PP复合材料相当;然而，GF在强度方面仍然优于GF。旋转和毛细管流变仪分析确定了所有配方的粘度，显示玄武岩复合材料的粘度始终低于玻璃纤维复合材料，表明更容易的加工条件。
A growing concern of climate change and waste pollution is causing a shift in products towards green materials. The automotive industry is exploring environmentally friendly alternatives to glass fibers (GF). This research focuses on understanding interactions between constituents of biocomposites made up of basalt fiber (BF) and hemp hurd particle fiber (HF) reinforced polypropylene (PP), and statistically comparing the mechanical properties. The addition of a coupling agent has significantly improved the performance and fiber-matrix interactions in the biocomposite blends. The elastic modulus of some BF/HF/PP mixtures were comparable to the GF/PP composite; however, the GF still outperformed in strength. Rotational and capillary rheometer analysis determined the viscosities of all formulations displaying that basalt composites were consistently lower in viscosity than the glass fiber composite, indicating easier processing conditions.
