Thermoplastic Composite Manufacturing Cost Analysis

Abstract

Continuous fiber‐reinforced thermoplastics (CFTs) present some key advantages over thermosetting matrix composites, being characterized by recyclability, indefinite shelf life, and a significant potential for high volume production, associated with low costs. Short and long fiber‐reinforced thermoplastics obtained mainly using commodity polymer as matrices are already widely used in low technology applications. CFT applications are still limited, although in some cases notably for their technological value. This arises either from very high raw material costs or from not fully assessed processing routes. This review essentially focuses on the cost issues associated with the production of CFT parts in comparison with thermosetting matrix composites characterized by similar properties. Some cost models are reviewed, and the relationship between performances and costs is highlighted as a key feature for the choice of CFT. Their use in substitution of thermosetting matrix composites and metals is strictly related to raw materials cost, manufacturability at cost‐effective conditions, and availability of design data and test methodologies. CFT, characterized by shorter processing time than those required for thermosetting matrix composites, already offers promising solutions in many applications.

Innovating routes for the reused of PP-flax and PP-glass non woven composites: A comparative study

“…Some sectors, such as the automobile, have implemented drastic regulations to comply with standards and European directives [1] that promote end-of-life treatment through the recyclability of materials [2e4]. In response, the design of mechanically recyclable composites involves the development of thermoplastic matrices instead of thermoset resins [5].…”
