Abstract:This paper aims to conduct theoretical modeling of tensile properties of thermoplastic composites developed from novel unidirectional recycled carbon fiber tapes. Unidirectional recycled carbon fiber tape structure is an innovative, sustainable and cost-efficient prepreg structure designed to develop carbon fiber reinforced plastics with the highest resource efficiency. In order to do modeling, existing theoretical models of tensile properties of unidirectional composites were reviewed in the first part of thi… Show more

Technological developments in the processing of staple carbon fiber disclosed that producing hybrid yarn with improved homogeneity, uniformity, compactness and orientation can fully utilize the potential in high-performance composites. Therefore, developing hybrid yarn structures through yarn formation technology has become an emerging trend in the past few years. The present paper aims to highlight the recent development in the yarn formation technology for producing innovative yarn structures from staple carbon and thermoplastic fibers for high-performance fiber-reinforced plastics. For this purpose, pre-spinning, spinning and post-spinning operations of yarn formation technology are reviewed to technological aspects and processing of staple carbon fiber. Furthermore, recent developments in developing flyer, friction and wrap-spun hybrid yarn for high-performance composites are also presented in this paper. An attempt is carried out to develop the relationship between hybrid yarn structures and composite properties. The comparison of tensile properties of thermoplastic plastic composites shows that composite based on hybrid yarn structure possesses 300% and 700% higher tensile strength compared to nonwovens and injection molding composites.

The aim of this study was to characterise the microstructural organisation of staple carbon fibre-reinforced polymer composites and to investigate their mechanical properties. Conventionally, fibre-reinforced materials are manufactured using continuous fibres. However, discontinuous fibres are crucial for developing sustainable structural second-life applications. Specifically, aligning staple fibres into yarn or tape-like structures enables similar usage to continuous fibre-based products. Understanding the effects of fibre orientation, fibre length, and compaction on mechanical performance can facilitate the fibres’ use as standard engineering materials. This study employed methods ranging from microscale to macroscale, such as image analysis, X-ray computed tomography, and mechanical testing, to quantify the microstructural organisations resulting from different alignment processing methods. These results were compared with the results of mechanical tests to validate and comprehend the relationship between fibre alignment and strength. The results show a significant influence of alignment on fibre orientation distribution, fibre volume fraction, tortuosity, and mechanical properties. Furthermore, different characteristics of the staple fibre tapes were identified and attributed to kinematic effects during movement of the sliver alignment unit, resulting in varying tape thicknesses and fuzzy surfaces.
