Toward Polymeric and Polymer Composites Impeller Fabrication

Abstract

Impellers are referred to as a core component of turbomachinery. The use of impellers in various applications is considered an integral part of the industry. So, increased performance and the optimization of impellers have been the center of attention of a lot of studies. In this regard, studies have been focused on the improvement of the efficiency of rotary machines through aerodynamic optimization, using high-performance materials and suitable manufacturing processes. As such, the use of polymers and polymer composites due to their lower weight when compared to metals has been the focus of studies. On the other hand, methods of the manufacturing process for polymer and polymer composite impellers such as conventional impeller manufacturing, injection molding and additive manufacturing can offer higher economic efficiency than similar metal parts. In this study, polymeric and polymer composites impellers are discussed and conclusions are drawn according to the manufacturing methods. Studies have shown promising results for the replacement of polymers and polymer composites instead of metals with respect to a suitable temperature range. In general, polymers showed a good ability to fabricate the impellers, however in more difficult working conditions considering the need for a substance with higher physical and mechanical properties necessitates the use of composite polymers. However, in some applications, the use of these materials needs further research and development.

Stereolithography of (meth)acrylate‐based photocurable resin: Thermal and mechanical properties

“…Generally, in this method, fabrication of the part completed by placing one layer of material on top of the other. 1,2 Among the various methods in 3D printing, stereolithography (SLA) due to the high accuracy, smooth surface finishing, the ability to produce transparent objects, and the incorporation of fine details, for example, compared to the fused deposition modeling has been the center of attention of studies. [3][4][5] In this method scanning the resin surface by a laser, which is programmed before, can cause polymerization or cross-linking and leads to the fabrication of the parts.…”

A Decision-Making Carbon Reinforced Material Selection Model for Composite Polymers in Pipeline Applications

“…After completion, the structure can be manually or chemically removed from the print platform by destroying the support structure [25,[55][56][57]. Fused deposition modeling (FDM) or material extrusion additive manufacturing are other names for this process that are permissible in Each tensile sample of PETG carbon fiber takes a minimum of 9 minutes and a maximum of 10 min for printing the ASTM D638.…”

Challenges and Opportunities in Additive Manufacturing Polymer Technology: A Review Based on Optimization Perspective

“…Each polymer raw material has its unique properties, for example, PLA is a biodegradable material [44], and ABS is a toxic material [45]. So, it is used in many applications like medical [46], pipe making [47], and impeller making [48] based on the raw material properties. A previous literature review revealed that the FDM-fabricated impeller of the rotodynamic hydraulic pump performed similarly to the original impeller.…”
