“…These researchers reported process chains for product development rather than technological developments of carding. [39][40][41][42] Later, technological developments in longstaple carding machines were initiated by considering special properties of staple carbon fibers. For this purpose, the design of a laboratory scale-carding machine has been modified, optimized and adjusted.…”

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.

“…Molding pressure higher than minimal molding pressure exceeds the max pressure the ber network can take and will not cause further voids closing but matrix percolation. Matrix percolation will cause the actual ber content to exceed V f [17] . Thus, the void content of composites (with a ber content of V f ) prepared under molding pressure higher than will be considered as 0, that is:…”

“…Dry-laid, such as carding [2][3][4] , and wet-laid [5,6] , are the two widely-used methods to prepare nonwoven preform. Compared with the dry-laid nonwoven process, the wet-laid nonwoven process can prepare nonwoven composites with more uniform ber distribution [7] , which may result in better mechanical performance.…”

Various wet-laid nonwoven composites have been well-developed in recent decades. However, studies that systematically investigate the factors affecting the void content of wet-laid nonwoven composites are still missing. This paper aims to study the factors affecting the void content of wet-laid nonwoven composites and propose a mechanism for void elimination in wet-laid nonwoven composites. Polypropene (PP) and carbon fiber (CF) were chosen to manufacture PP/CF wet-laid nonwoven composites. An orthogonal experimental design found that the CF content and molding pressure can dominate the void content while molding temperature and time have non-significant effects. Subsequently, this paper proposed that the void elimination mechanism is the compression of impregnated CF network (compression mechanism) instead of the matrix’s infiltration to the dry CF network (infiltration mechanism). In order to validate the compression mechanism, the compression curve of the dry CF network was transformed into curves predicting the void content of the PP/CF nonwoven composites. Comparing the predicted and experimental void content suggests that void elimination follows the compression mechanism.

“…However, the strength was reduced relative to the neat glass fiber composites due to poor load transfer to the carbon fiber tows. Wei et al [96] produced hybrid wet-laid nonwoven textiles using 6 mm recycled T800 carbon fibers, 13 mm glass fibers, and PA6 fibers. Glass fibers were mixed at 1%, 2%, and 5% fiber volume fraction and compression molding was used to produce plates with 20% total fiber volume fraction for flexural and IZOD impact testing.…”

Carbon fiber recycling has garnered significant attention in recent years due to the large volume of manufacturing waste and upcoming end-of-life products that will enter the waste stream as the current generation of aircraft is retired from service. Recycled carbon fibers have been shown to retain most of their virgin mechanical properties, but their length is generally reduced such that continuous fiber laminates cannot be remade. As such, these fibers are typically used in low-performance applications including injection molding, extrusion/compression molding, and 3D printing that further degrade the fiber length and resulting composite properties. However, recent advances in the processing of long discontinuous fiber textiles have led to medium- to high-performance composites using recycled carbon fibers. This review paper describes the recent advances in recycled carbon fiber textile processing that have made these improvements possible. The techniques used to manufacture high-value polymer composites reinforced with discontinuous recycled carbon fiber are described. The resulting mechanical and multifunctional properties are also discussed to illustrate the advantages of these new textile-based recycled fiber composites over the prior art.
