Aligned discontinuous intermingled reclaimed/virgin carbon fibre composites for high performance and pseudo-ductile behaviour in interlaminated carbon-glass hybrids

Reclaimed Carbon and Flax Fibre Composites: Manufacturing and Mechanical Properties

“…Figure 11 compares the 100% rCF and the flax/rCF hybrid ADFRC characteristic and measured properties. As in [37], the 100% rCF ADFRC manufactured with the HiPerDiF technology display high primary mechanical properties, i.e., stiffness and strength. However, it is interesting to notice the effect of flax fibres addition.…”

“…Concluding, flax/rCF intermingled hybrid materials manufactured with the HiPerDiF method can be a viable solution in applications where a reduction of primary mechanical properties is an acceptable trade-off for the increase of functional properties and cost reduction. As in [37], the 100% rCF ADFRC manufactured with the HiPerDiF technology display high primary mechanical properties, i.e., stiffness and strength. However, it is interesting to notice the effect of flax fibres addition.…”

“…The proviso being that the fibres are accurately aligned, and their length is sufficiently long compared to the critical fibre length [35]. Remanufacturing reclaimed fibres with the HiPerDiF method allows on one hand the production of high-performance recycled carbon fibre composites, thanks to a high level of fibre alignment, and on the other the ability to deal with the geometric characteristics of reclaimed carbon fibres [36,37]. Longana et al also proposed a quality control and property assurance methodology for reclaimed carbon fibres based interlaminated hybrid specimens produced with the HiPerDiF technology [38].…”

Modelling hybrid effects on the stiffness of aligned discontinuous composites with hybrid fibre-types

“…with intimate intermingling of fibre-types), and extends further the ability to tailor the properties of composites in terms of stiffness, strength or toughness [1][2][3]. Hybrid discontinuous composites have already been manufactured [2][3][4][5] and confirmed the advantages listed previously; however, "hybrid effects" can be observed in the experimental data of hybrid discontinuous composites, not only in the measured strength and failure strain, but also on the stiffness [2][3][4]6].…”

Development of a closed-loop recycling process for discontinuous carbon fibre polypropylene composites

“…Yu et al showed that the HiPerDiF method can provide preforms with 67 % of fibres aligned within a range of ±3 o and mechanical performance comparable with those of an equivalent continuous fibre composite [24]. Longana et al also applied the HiPerDiF method to the remanufacturing of rCF achieving one of the highest mechanical performances reported in the literature for a recycled composite material [25]. Longana et al also used the HiPerDiF method to investigate the performance of composites remanufactured from short carbon fibres that have undergone multiple recycling loops [26].…”
