Mechanical Properties of Recycled Carbon Fibre

Şubat 21, 2022
Kompozitlerde yüksek değerli karbon fiberin artan kullanımı, artan atık üretimi ile bağlantılıdır. Ayrıntılı bilgi almak için aşağıdaki linke tıklayınız.
The increasing use of high-value carbon fibre in composites is linked with increasing waste generation: from dry fibre and prepreg offcuts during manufacturing to end-of-life parts.
In this work, a novel thermoplastic tape was produced from 60 wt.% manufacturing waste carbon fibres (60 mm long) and 40 wt.% polyester (PET) fibres using a thermal consolidation technique.
The thin (0.2 mm) and narrow (20 mm wide) tapes were then used to fabricate laminated composite panels in two 0/90 tape architectures: cross-ply and woven ply.
Various mechanical properties, including tensile, flex ural, compression, and impact, were evaluated. It was found that cross-ply performed better th an woven ply laminates, with failure in the latter materials typically initiating at the tape interlacement points.
