Development of glass fiber-PET hybrid yarn for thermoplastic composites / Melis Eldem Heper in CHEMICAL FIBERS INTERNATIONAL, Vol. 72, N° 2 (05/2022)  

[article]  inCHEMICAL FIBERS INTERNATIONAL > Vol. 72, N° 2 (05/2022) . - p. 69-70 Titre : Development of glass fiber-PET hybrid yarn for thermoplastic composites Type de document : texte imprimé Auteurs : Melis Eldem Heper, Auteur Année de publication : 2022 Article en page(s) : p. 69-70 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Composites à fibres Composites à fibres -- Propriétés mécaniques Composites thermoplastiques Essais de résilience Essais dynamiques Fibres continues Fibres de verre Mélanges de fibres Polyéthylène téréphtalate Index. décimale : 677.4 Textiles artificiels Résumé : The interest and demand towards the use of thermoplastic composites have been gradually increasing due to their high damage tolerance, recycling, and energy absorption capability compared to thermoset composites. Despite such positive properties, thermoplastic materials have a negative side, which is their high melt viscosity. The solution to this problem can be achieved by using hybrid yarns in which reinforcement and matrix fibers are homogeneously mixed together. In this work, the aim was to investigate the mechanical properties of thermoplastic composites to be prepared using continuous glass fiber/polyethylene terephthalate (CGF/PET) hybrid yarns in different proportions by volume. CGF/PET hybrid yarns containing glass fiber in different volumes (450/0 and 550/0) were produced, woven and then transformed into thermoplastic composite test plates using hot press. Tensile, 3 point bending and impact tests were used to investigate the mechanical properties.
