In this paper, a series of polymer composites made from acrylonitrile-styrene-acrylate (ASA) and poly (ether ether ketone) (PEEK) were manufactured. ASA acts as a polymer matrix while PEEK is loaded in the form of micro-particles that act as a reinforcing filler. The composites were compounded by single screw extrusion and then, different specimens were manufactured either via injection moulding (IM) or fused filament fabrication (FFF). Two different types of PEEK (commercial and reused) in different concentrations (3 and 6 wt.%) were tested and their influence in the mechanical, structural, and thermal properties were studied. It was observed that reused PEEK enhanced the stiffness and tensile strength and thermal stability of the composites both, for injected and printed specimens. This evidences the suitability of these composites as potential candidates as novel materials with enhanced properties following an approach of circular economy.
在本文中，制备了一系列由丙烯腈-苯乙烯-丙烯酸酯（ASA）和聚醚醚酮（PEEK）制成的聚合物复合材料。ASA作为聚合物基体，而PEEK以微粒形式负载，作为增强填料。复合材料通过单螺杆挤出进行混合，然后通过注塑成型（IM）或熔融长丝制造（FFF）制备不同的试样。测试了两种不同类型、不同浓度（3重量%和6重量%）的PEEK（商业级和回收级），并研究了它们对复合材料力学、结构和热性能的影响。结果表明，对于注塑和打印试样，回收级PEEK均提高了复合材料的刚度、拉伸强度和热稳定性。这证明了这些复合材料作为遵循循环经济方法的具有增强性能的新型材料的潜在候选材料的适用性。
