The paper presents studies on the use of waste from wind turbine blades (WTBs) in the production of thermoplastic composites and regranulate-based products of acrylonitrile-butadiene-styrene (ABS) copolymers. Composites containing two types of WTB fractions (finely milled fraction-GRm and dust fraction-GRd) were produced using a co-rotating twin-screw extruder. During extrusion, different screw configurations of the plasticizing system as well as different material formulations were investigated. The studied composites contained from 10 to 70 wt% of shredded WTB, as well as up to 15 wt% of additional components, mainly those improving impact strength and processing properties. It was found that the individual WTB fractions generally deteriorate the mechanical properties of ABS. However, a composite containing 30 wt% GRm and modified with an additional 7 wt% ACM-G2 (impact modifier type) can be hot-pressed into good quality panels. It can also be successfully used to produce profiles in the extrusion process, mainly due to its significantly reduced viscosity. The studies presented in this article showed one of the possible ways of using WTB waste. It is advantageous because it uses WTB waste in a thermoplastic ABS matrix, which is also a secondary raw material. As a consequence of this, a completely new composite material based wholly on secondary raw materials can be obtained, which can be subjected to multiple processing.
本文介绍了关于将风力涡轮机叶片（WTB）废料用于生产热塑性复合材料以及丙烯腈 - 丁二烯 - 苯乙烯（ABS）共聚物再生粒料基产品的研究。使用同向旋转双螺杆挤出机制备了含有两种类型WTB级分（细磨级分 - GRm和粉尘级分 - GRd）的复合材料。在挤出过程中，研究了塑化系统的不同螺杆配置以及不同的材料配方。所研究的复合材料含有10至70重量％的切碎WTB，以及高达15重量％的附加组分，主要是那些改善冲击强度和加工性能的组分。发现单个WTB级分通常会降低ABS的机械性能。然而，含有30重量％GRm并额外用7重量％ACM - G2（冲击改性剂类型）改性的复合材料可以热压成质量良好的板材。它还可以成功地用于挤出过程中生产型材，主要是因为其粘度显著降低。本文提出的研究展示了使用WTB废料的一种可能方式。这是有利的，因为它在热塑性ABS基体中使用WTB废料，而热塑性ABS基体也是一种二次原料。因此，可以获得一种完全基于二次原料的全新复合材料，该复合材料可以进行多次加工。
