Abstract Balancing the performance, durability and safety requirements of automotive systems with the regulatory landscape in an environment of climate change has accelerated the search for sustainable fiber reinforced polymer composites for automobile structures. Glass fiber reinforced thermoplastic polymer composites (GFRP) are widely used in certain structures like front end modules and liftgate; However, they cannot be used in more demanding applications due to their low mechanical properties. Carbon fiber reinforced thermoplastic polymer composites (CFRP) are promising candidates for applications like bonnet, but their use is constrained by cost. Basalt fiber reinforced thermoplastic polymer composites (BFRP) are sustainable materials that can be positioned between GFRP and CFRP in terms of performance and cost-effectiveness. The mechanical performance of the BFRP depend on the quality of the fiber-matrix interface that aids in efficient load transfer from the matrix to the fiber. Typically, basalt fibers are inert in nature and need treatments to improve its adhesion to polymeric matrices. The major chemical treatments that are reviewed in this article include matrix functionalization, silane treatment, functionalized nanomaterial coating and plasma polymerization. The physical treatments reviewed include plasma treatment and milling. It is evident that chemically treating the basalt fiber with a functionalized nanomaterial yields BFRP with a good stiffness – toughness balance that can be used for challenging metal replacements as also in new emerging areas like sensing and 3D printing.

用于汽车复合材料的玄武岩纤维的表面处理

摘要 平衡汽车系统的性能、耐用性和安全要求与气候变化环境中的监管环境，加速了对用于汽车结构的可持续纤维增强聚合物复合材料的探索。玻璃纤维增​​强热塑性聚合物复合材料（GFRP）广泛用于前端模块和举升门等某些结构；然而，由于它们的低机械性能，它们不能用于要求更高的应用。碳纤维增强热塑性聚合物复合材料 (CFRP) 是发动机罩等应用的有希望的候选材料，但其使用受到成本的限制。玄武岩纤维增强热塑性聚合物复合材料 (BFRP) 是可持续材料，在性能和成本效益方面可介于 GFRP 和 CFRP 之间。BFRP 的机械性能取决于纤维-基体界面的质量，该界面有助于有效地将载荷从基体转移到纤维。通常，玄武岩纤维本质上是惰性的，需要进行处理以提高其对聚合物基体的附着力。本文综述的主要化学处理包括基体功能化、硅烷处理、功能化纳米材料涂层和等离子体聚合。审查的物理处理包括等离子处理和铣削。很明显，用功能化纳米材料对玄武岩纤维进行化学处理会产生具有良好刚度 - 韧性平衡的 BFRP，可用于具有挑战性的金属替代品以及传感和 3D 打印等新兴领域。
